Crucitorn, a Jedi Master within the Jedi Order, participated in the Battle of Nar Shaddaa. This conflict, occurring before 68 BBY, pitted the Jedi against the Flame-Wielders. During the battle, Crucitorn was set ablaze by his enemies, yet he demonstrated incredible resilience, withstanding the agony and retaliating. Approximately in 68 BBY, Jedi Master Dooku referenced Crucitorn's ordeal to illustrate pain tolerance to his Padawan, Qui-Gon Jinn.
Subsequently, Dooku shared details of his exchange with Jinn in a holo-letter addressed to his sister, Jenza. Circa 23 BBY, Dooku entrusted several data disks containing his correspondence with Jenza to Asajj Ventress, his newly appointed Sith assassin, tasking her with an investigation to discover his sister's whereabouts; Ventress then listened to the holo-disk referencing Crucitorn.
The audio drama Dooku: Jedi Lost, penned by Cavan Scott and released on April 30, 2019, mentioned Crucitorn. The audio drama's script, which was released on October 1, 2019, verified the spelling of Crucitorn's designation.
