Lyssa Drak

Created within DC Comics continuity, Lyssa Drak first appears as a Talokian affiliated with the Sinestro Corps. She functions as the corps' trainer/recorder, charged with testing recruits in the Fear Lodge and documenting outcomes in the Book of Parallax, which is physically chained to her. During the Blackest Night / Brightest Day era of Green Lantern storylines she is sealed into the Book of the Black, later freed by Krona (a robed stranger figure in the narrative) and assigned as keeper of that book for a time before returning to interactions with the Sinestro Corps in subsequent crossovers.

Sources identify Lyssa Drak as a female-presenting Talokian character typically depicted in association with Sinestro Corps regalia (the yellow motif and corps uniform as used by Yellow Lantern members). Comic and media appearances portray her as a Talokian alien figure recognizable by readers and viewers; specific anatomical measurements, colors, or exhaustive visual detail are not provided in the cited summaries. She is commonly illustrated carrying or bound to the Book of Parallax when serving her recorder role, and later is visually linked to the Book of the Black during the Blackest Night storyline.

Lyssa Drak wields a Sinestro Corps yellow power ring and employs its standard ring functions: creation of constructs based on imagination, flight, force fields, and related ring capabilities as demonstrated in Green Lantern stories. Within narratives she is described as a trainer and survivalist figure who conducts Fear Lodge trials, records recruits' outcomes in the Book of Parallax (the book is chained to her), resists interrogation by telling tales, and performs duties of safeguarding and updating the Book. Her narrative arc includes being imprisoned (Sciencell, lantern-powered cages), being sealed into the Book of the Black, and later being freed to act as that book's keeper for a period.
