Ancestry: Siren
Sirens are at home along the waters of the sea. They settle on rocky coasts and remote islands, and even on floating piles of kelp. Sirens are mercurial creatures who can turn in an instant from lonely to repulsed, from desirous to hateful, from welcoming to irritated, from loving to murderous—and then back again. They are fascinated with ships, and enjoy toying with them. One siren might call out to a passing crew for company, only to capriciously draw the ship into an entangling mass of kelp. Another might lure a vessel onto jagged rocks so as to study the wreckage and learn more about the strange contraption. Over the years, a growing number of sirens have decided to satisfy their curiosity by taking positions on ship crews, including even the position of captain.
Sirens are half-humanoid half-fish creatures with an upper human body and long fish tails. They have rubbery, scaly skin, pointed teeth, and fins on their cheeks. They have long hair in all colors. Their eyes are hazel, blue, green, or purple.
