"Poison Moon" consisted of a brief, four-installment comic series featured within issues 44 through 47 of Dark Horse Extra. The writing was done by Michael Carriglitto, the illustrations were created by Adrian Sibar, and the coloring was handled by Dan Jackson.
Obi-Wan Kenobi and [Anakin Skywalker](/article/anakin_skywalker-legends], both Jedi Knights, were looking into a distress call originating from the wreckage of a Consular-class space cruiser, where they discovered the entire crew had perished. As they examined the vessel, they came across Alysun Celz, a woman in hiding. She attempted to fire upon them, but they managed to take her weapon. Celz identified herself as the ship's pilot and claimed they had been transporting a Dark Jedi named Et Rex. Obi-Wan proceeded to search the ship and located Et Rex, who attempted to intimidate Kenobi using mynocks, unaware of his Jedi status. Et Rex then revealed that Celz was, in fact, the Dark Jedi. Simultaneously, Celz incapacitated Skywalker by using Force lightning. Rex and Kenobi arrived back just in time, employing mynocks to restrain her.
