Preface

The moon keeps me company in the quiet
hours of the night, as I begin writing this document. The world of Lyyth has existed only in my mind and in the minds of my attentive players for long now, and as the days stretch to years, the impetus to put this world down on paper only grows stronger. This setting has been a vehicle for so many fond and powerful memories, and the contents of this book serve as a primer for those who wish to understand this setting.

The Gods of Lyyth

As with most settings, religion plays a key role in the lives of the people of Lyyth. However, unlike most standard settings, the gods of Lyyth do not openly walk the world or meddle with the events that transpire within it. Indeed, the existence of the gods themselves is a mystery that none can confirm nor deny.

Divine providence and the existence of higher beings, known to most as gods, is a topic which those on the continent of Lyyth do not universally agree on. Supernatural phenomena can be attributed to the doings of a divine entity by those who worship such a god, but it is not uncommon for different religions within Lyyth to claim the same events as evidence of their own gods' prowess or benevolence.

Within Lyyth, the basis for worshipping a god arises not from witnessing one's existence and intentions, but rather from the power of belief in the existence of such a being, however accurate that belief may be. The different worships of Lyyth form a patchwork of religious and political organizations, with each organization striving toward its own goals. The power and influence of such an organization arises not from the purported capabilities of any god, but rather on the organization's ability to influence, control, and manipulate people and events to its advantage. Thus, the strength of a god's following depends primarily on who its believers are, how many they number, and what places their influence can be exerted.

Chapter 4: Classes

The adventurers of Lyyth assume the
forms of many of the classes presented in
the Player's Handbook. This chapter
expands on the subclass options available
to most of the classes, and describes the
roles, places, and ideals that each subclass
takes within the world of Lyyth.

Barbarian: Primal Path

At 3rd level, a barbarian gains the Primal Path feature. The following options are available to a barbarian, in addition to those offered in the Player's Handbook and other books: the Path of the Summit, the Path of the Thundering Horde.

Path of the Summit

The great mountains go by many names: the Dragon's Spine, Mount Drakholm, the Great Divide. Those that walk the Path of the Summit are those who forged by the mountains' crushing stones and frigid winds. Typically, barbarians of this path come from one of the four goliath clans, or "Agu", within the mountain range. Although most barbarians that adopt this path are goliaths, the clans occasionally take in individuals of other races, training and raising them as they would their own.

Optional Restriction: Goliaths Only

The Path of the Summit is typically followed by goliath of the great mountains' four clans.

To lift this restriction, work with your DM to establish how a non-goliath character came to follow this path, and who instructed and trained the character in this path's techniques.

Strength of Stone

When you choose this path at 3rd level, you gain the ability to transform yourself into stone, both to deflect blows and to add weight to your own. You gain the following benefits while you are raging.

• When you hit with a melee weapon attack, you can transform yourself into stone to impart extra power into your strike, becoming petrified until the start of your next turn. The attack deals an additional 1d12 damage and if the target is a Huge or smaller creature, it must succeed on a Strength saving throw or be pushed up to 10 feet away from you and knocked prone. The DC for this saving throw is equal to 8 + your proficiency bonus + your Strength modifier.
• When an attacker that you can see hits you with an attack, you can use your reaction to transform yourself into stone to deflect the blow, becoming petrified until the start of your next turn. When you do so, the damage you take from the attack is reduced by 1d12 + your Constitution modifier + your barbarian level. You can also use this feature as a reaction when an effect would push you or knock you prone in order to prevent the effect.

Titan's Leap

At 6th level, you can channel the strength of giants into your legs, empowering your leaps. When you take the Dash action on your turn, the distance you can jump increases by a number of feet equal to your barbarian level until the end of your turn. Additionally, your jump distance is tripled while you are raging.

Unchillable

At 10th level, you have developed an endurance against the snow and ice of the mountains' peaks. All cold damage you take is reduced by an amount equal to your Constitution modifier, and you gain resistance to cold damage while you are raging.

Shifting Stone

Beginning at 14th level, the might of the great mountains allows you to bend stone to your will. While you are raging, you can move and speak as normal while petrified, and being petrified doesn't impose advantage on attacks against you, cause you to automatically fail Strength or Dexterity saving throws, or cause you to become incapacitated or unaware of your surroundings.

Additionally, you can cast stone shape without expending a spell slot. Once you cast the spell with this feature, you can't cast it with this feature again until you finish a long rest.

PART 2 | CLASSES

Path of the Thundering Horde

Trained as leaders and tacticians, those who walk the Path of the Thundering Horde lead their allies to victory with deafening and furious roars. The Path of the Thundering Horde is an ancient tradition developed by goliaths hailing from the halls of the mighty storm giants of Jhara Pahara. Traditionally allied with the Clan in Blue of Daag'Dreya, the teachings of the warriors of the horde have long since been spread to others.

Bard: Bard College

At 3rd level, a bard gains the Bard College feature. The following option is available to a bard, in addition to those offered in the Player's Handbook and other books: the College of Linguistics.

Ignan

Spell. When you cast a spell that requires concentration, you can shroud yourself with flames. While you maintain concentration on that spell, a creature that touches you or hits you with a melee attack while within 5 feet of you takes fire damage equal to the spell's level + your Charisma modifier.
Inspiration. When you inspire a creature, each creature within 5 feet of the target of your Bardic Inspiration takes 1d6 fire damage when they use their Inspiration die.

Infernal

Spell. When you deals damage to a creature with a spell, you can infuse it with hellish energy. Choose one creature that took damage from the spell. Any healing the target receives until the start of your next turn is reduced by 1d4 for each level of spell slot used to cast the spell.
Inspiration. You can attempt to inspire a hostile creature. That creature must make a Wisdom saving throw against your spellcasting save DC or have any healing it receives reduced by your Inspiration Die. The creature can repeat the saving throw at the start of its turn, ending the effect on a success.

Terran

Spell. When you cast a spell that requires concentration, you can strengthen your connection to the ground. While you maintain concentration on that spell and are standing on earth or stone, you cannot be pushed or knocked prone.
Inspiration. When you inspire a creature, the target of your Bardic Inspiration cannot be pushed or knocked prone if they are standing on earth or stone while they have the Inspiration Die.

Sylvan

Spell. When you cast a spell while within 60 feet of a plant, you can cast the spell as though you were in the plant's space, but you must use your own senses.

Druid: Druid Circle

Circle of the Wardens

The Circle of the Wardens is tasked with the defense of the sanctity of nature. Known as wardens, druids of this circle practice a unique form of martial arts, setting them apart from their contemporaries.

On the continent of Lyyth, three different factions of wardens exist: the sand guardians of the Gali Desert, the wood wardens of the Moorewoods, and the white wardens of the continent's furthest northern reaches.

Knight Banneret

As kingdoms raise armies and cross blades, bannerets flying battle standards lead these armies in the field. Burdened with this critical task, these knights bear the heavy weight of the safety and wellbeing of their soldiers, and the responsibility of bringing forth a victory.

Monk: Monastic Tradition

At 3rd level, a monk gains the Monastic Tradition feature. The following options available to a monk, in addition to those offered in the Player's Handbook and other books: the Way of the Dragon, the Way of the Hidden Fist, the Way of the Wild.

Paladin: Sacred Oath

At 3rd level, a paladin gains the Sacred Oath feature. The following options are available to a paladin, in addition to those offered in the Player's Handbook and other books: the Oath of Rebellion and the Oath of Steel.

Oath of Steel

The Oath of Steel is an oath less rooted in formality and dedication than other oaths, and functions more as a mantra or way of life. Rather than placing faith in gods or glory, knights who take this oath place great importance on their arms and armor, paying care and respect to the equipment that ultimately keeps them alive.

Across the continent of Lyyth, this oath is commonly adopted by mercenaries and sellswords. Many paladin who follow this oath are veterans and former soldiers, and can be found for hire as bodyguards or mentors.

Chapter 5: Personality and Background

The cultures and peoples of Lyyth pro-
duces a number of special situations and events, which may affect a character's background. This chapter expands on the background options and feats presented in the Player's Handbook, and can be used to find the character's place in the world.

Crusade Orphan

The First and Second Crusades brought many young men and women into its fold, ultimately costing them their lives. The result: a generation of broken families or orphans, many of whom were taken in by the Order of Bahamut, who orchestrated the crusades.

As the child of one that lost to the crusades, your upbringing might have been significantly influenced by the Order of Bahamut. Perhaps you bear resentment toward the order for what they've caused. Perhaps the order raised you.

• Skill Proficiencies: History, Religion
• Languages: Choose two from Abyssal, Celestial, Draconic, Giant, or Infernal
• Equipment: A holy symbol bearing the six-winged dragon crest of Bahamut, a set of common clothes, and a belt pouch containing 15 gp

Wyrmurrin Freeman

Much to the distaste of the rest of Lyyth, the Wyrmurrin Empire's century-old practice of military expansion and enslavement continues to thrive. These prisoners taken from the empire's invasive expansion into neighboring lands are brought back to the heart of the empire, where they spend years or decades in servitude of a dragonborn family within the empire.

Though the empire's laws allow slavery, it places a strict set of laws on the duration and process of enslavement. Prisoners are to be subjected to no more than twelve years of initial service. Although slaves are protected from certain forms of abuse, certain criminal acts can result in the slave's service being extended, sometimes even doubled or tripled. Intended to discourage rebellion, the system is often abused by slave-owners in order to retain control over their slaves.

Within the empire's slavery laws exists the Freeman system, a method for slaves to end their service and to become integrated with the Wyrmurrin Empire as citizens. To become a Freeman, a slave must receive sponsorship from a dragonborn family, effectively becoming adopted by the family. A slave can begin seeking sponsorship at any time, but can't receives sponsorship from a third party family until completion of service. Slaves that don't receive sponsorship within a year of the end of their service are exiled from the empire, or can choose to voluntarily extend their service.

• Skill Proficiencies: Choose two from Acrobatics, Animal Handling, Athletics, Intimidation, and Performance
• Tool Proficiencies: One type of artisan's tools
• Languages: Draconic
• Equipment: A set of common clothes, a dragonstone ring of sponsorship, and a belt pouch containing 10 gp

Variant: Escaped Wyrmurrin Slave

A system of slavery does not function if all slaves are freed. You might not have yet achieved freemen status, or may have come into conflict with the dragonborn family you served, crushing any hope of being sponsored. If you wish to be an escaped slave, choose the Rebel's Hospitality feature (see the sidebar) instead of the Freeman Sponsorship feature.

Rather than a dragonstone ring of sponsorship, you can start with a set of manacles.

Chapter 6: Treasure

Flavor

Akkhayraeas

The ancient blue dragon, the storm drake Akkhayraeas, has long ago broken off flakes of his heartstone to seal away his various emotions. He created a total of four shards, containing within them his fear, empathy, sorrow, and trust. He then scattered these shards in various dens across the land. Each shard appears as a jagged sapphire-colored stone, arcing with electricity, and creates unnatural thunderstorms around it.

Kyur'Oa

The ancient green dragon, the venom drake Kyur'oa, has long ago broken off flakes of her heartstone to seal away her various emotions. She created a total of three shards, containing within them her sloth, gluttony, and pride. She then gifted these shards to her most trusted followers. Each shard appears as a jagged emerald-colored stone, fuming with toxic gas, and causes plants to wither around it.

A Demon's Flame

Inside each fiend lies a fiery core, a physical manifestation of their life force. When a fiend dies, it's core will begin to fade, with the flames of more powerful fiends lingering the longest. The demon generals discovered that by feasting upon the demon flames of their enemies, they could increase their own powers. Thus began a cycle of kill and be killed, wherein powerful demons slew others and then were slain in turn, and the power of many fiends were amassed into powerful demon's flames.

Wing Attack (Costs 3 Actions). Vor Erodia beats his wings. Each creature within 15 ft. of Vor Erodia must succeed on a DC 23 Dexterity saving throw or take 15 (2d6 + 8) bludgeoning damage and be knocked prone. Vor Erodia can then fly up to half its flying speed.

Detect. Vor Erodia makes a Wisdom (Perception) check.

Tail Attack. Vor Erodia makes a tail attack.

Acid Spit. Vor Erodia uses his acid spit.

Hellfire Breath (Costs 2 Actions). Vor Erodia exhales hellfire in a 90-ft cone. Each creature in that cone must make a DC 23 Dexterity saving throw, taking 66 (6d20) fire damage on a failed save, or half as much damage on a successful one.

The Beastmaster

Vor Erodia remained distrustful of other powerful fiends in general, and prefered the company of creatures of supposedly lesser intellect that he could control. The Pit Fiend survived the Order of Bahamut's crusade against hell by hiding behind his beasts in a far corner of Hell. Among his beasts, his favorite pets was a great black dragon named Khuzal'Khan.

The Skyrender

Needless to say, Khuzal'Khan did not take kindly to being ruled over, much less by a cowardly Pit Fiend. The great black dragon waited until his master's guard was down before striking and tearing him to shreds, which burned to ashes. From within the ashes, Khuzal'Khan plucked the flaming core of his old master, claiming the title of Vor Erodia.

Amphibious. The hydra can breathe air and water.

Multiple Heads. The hydra has five heads. While it has more than one head, the hydra has advantage on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious.

Whenever the hydra takes 25 or more damage in a single turn, one of its heads dies. If all its heads die, the hydra dies.

At the end of its turn, it grows two heads for each of its heads that died since its last turn, unless it has taken a specific type of damage since its last turn: fire for the white head, cold for the green head, poison for the blue head, lightning for the black head, and acid for the red head.

The hydra regains 10 hit points for each head regrown in this way. Each of the new heads is the same color as the ones that were removed.

Reactive Heads. For each head that the hydra has beyond one, it gets an extra reaction that can only be used for opportunity attacks.

Wakeful. While the hydra sleeps, at least one of its heads is awake.

Actions

Multiattack. The hydra makes as many bite attacks as it has heads.

Bite. Melee Weapon Attack: +12 to hit, reach 10ft., one target. Hit 12 (1d10 + 6) piercing damage and 6 (1d10) fire, cold, lightning, poison, or acid damage, depending on which head made the attack.

Breath Attacks

The hydra has as many breath attacks as it has heads, each with their own individual recharge. If it has a breath attack, it may forgo a bite attack in order to make a breath attack using that head. The hydra can only make one breath attack per turn.

Black - Acid (Recharge 6). The hydra exhales acid in a 60-ft. line that is 5-ft. wide. Each creature in that line must make a DC 21 Dexterity saving throw, taking 36 (8d8) acid damage on a failed save, or half as much damage on a successful one.

Blue - Lightning (Recharge 6). The hydra exhales lightning in a 60-ft. line that is 5-ft. wide. Each creature in that line must make a DC 21 Dexterity saving throw, taking 44 (8d10) lightning damage on a failed save, or half as much damage on a successful one.

White - Cold (Recharge 6). The hydra exhales cold in a 30-ft. cone. Each creature in that area must make a DC 21 Constitution saving throw, taking 45 (10d8) cold damage on a failed save, or half as much damage on a successful one.

Green - Poison (Recharge 6). The hydra exhales poison in a 30-ft. cone. Each creature in that area must make a DC 21 Constitution saving throw, taking 49 (14d6) poison damage on a failed save, or half as much damage on a successful one.

Red - Fire (Recharge 6). The hydra exhales fire in a 30-ft. cone. Each creature in that area must make a DC 21 Dexterity saving throw, taking 56 (16d6) fire damage on a failed save, or half as much damage on a successful one.

Optional Rule: Severed Head

The hydra's severed head may continue to squirm around and lash out at those around it. It thrashes like a worm and is unable to use its breath attack, but still has sharp teeth and a dangerous bite.

Each severed head has 10 hit points and an armor class of 17 as the hydra, but is considered prone and unable to get up. They act on the hydra's initiative and can make a single bite attack at an creature within 5 ft.

Various Magical Items

Blueflame Candlestick

Wondrous Item, Artifact, (requires attunement)

This brass candlestick holds a white wax candle, atop which burns a magical blue flame. The flame cannot be quenched in water nor suffocated by lack of air, and waxes and wanes almost as if breathing. This candlestick can be used as a spellcasting focus. While holding this candlestick, you gain a +1 bonus to spell attack rolls and to the saving throw DCs of spells that deal fire damage.

While attuned to the candlestick, all fire damage you do takes on the blue flame appearance, ignores resistance to fire damage, and treats immunity to fire damage as vulnerability instead.

As a bonus action while holding the candlestick, you can cause the candle's flame to take on the shape of any melee weapon that does not have the two-handed property. Attacks made with this weapon have a +1 bonus to attack and damage rolls, and deal fire damage instead of their normal damage type.

Sentience. The candlestick is a sentient true neutral object with an Intelligence of 19, a Wisdom of 16, and a Charisma of 16. It has hearing and darkvision out to a range of 120 feet. While attuned to this item, it speaks to you telepathically. It has an unquenchable thirst for knowledge, and will implore you to bring it to new places and show it new things. The sentience also harbors a hatred of all things fiendish. The sentience's name is Cyrus Kontzias, formerly a wizard of the Archmages' Tower.

Blueflame Sensor. The candlestick can create a blue flare in an unoccupied space it can see within 120 feet of its main form. Anyone who touches the sensor takes 1d4 fire damage. The Blueflame Candlestick can have more than 1 sensor, and can see and hear as if it were in its place.

The Blueflame Candlestick controls these sensors, and will be reluctant to snuff any of its sensors unless absolutely necessary. It may choose to divulge information discovered from these sensors to you if it chooses, but you are unable to control or see through the sensors.

Fuel the Flames. Whenever you kill a creature with fire, the candlestick gains one point of nourishment. When you take a long rest, the candlestick loses a point of nourishment for each sensor it currently has. If the candlestick does not have enough nourishment to sustain all its sensors, it can attempt to steal life from you. Make a DC 18 Constitution saving throw. On a failed save, you regain 1 less hit dice when you complete the long rest, and the Blueflame Candlestick gains one point of nourishment. It can attempt this a number of times equal to your level. If it does not have enough nourishment for its sensors, it must snuff out sensors until it can nourish all of them.
