The Draethos were a sentient race of humanoid beings. A member of this species was a Nihil Storm. Key features included sizable teeth, blue skin, black eyes, and hands with only four fingers. By the time of the Imperial Era, on Ossus, the skeletal remains of a Draethos were found slumped at the base of a large chair within their office, located in the Chamber of Antiquities of the Great Jedi Library. Two stone guardians stood as silent protectors, guarding the chamber against any who might intrude.
Regarding the new Star Wars canon, the Draethos were initially mentioned in the 2016 Star Wars: Force and Destiny sourcebook, Nexus of Power, which was produced by Fantasy Flight Games. Their first appearance was in The High Republic (2021) 7, a comic written by Cavan Scott, with illustrations by Georges Jeanty, and released by Marvel Comics on July 28, 2021. Within Star Wars Legends continuity, the Draethos were a species conceived by the combined efforts of authors Kevin J. Anderson and Tom Veitch, along with artist Chris Gossett, for the character Odan-Urr. They debuted in the comic Tales of the Jedi – Dark Lords of the Sith 3, published by Dark Horse Comics on December 1, 1994.
