Ancient Sith Armor

Type Armor, Enhanced,
Prerequisite: Force Sensitive
Requires Attunement: Yes

It consisted of a segmented torso armor shaped like a humanoid rib cage. Square, rigid-looking pauldrons covered the shoulders, the armpits, and part of the back. A flat-topped, visorless war helmet protected the head with a large, heart-shaped opening. A protective skirt of blade-shaped strips was worn around the waist.

At the time of the Cold War, many of those ancient suits of armor were still on display in the tombs of the Valley of the Dark Lords on Korriban. When they were still an apprentice, the Empire's Wrath found one such armor in the Tomb of Naga Sadow. It lay in a Sith sarcophagus along with an ancient lightsaber, still containing the corpse of a long-dead Sith Lord. Another was stored amongst other artifacts in Darth Thanaton's private library.
