Prokreisha was a Humanoid male, strong in the Force, and thus Force-sensitive. He underwent training under the auspices of the Jedi Order, ultimately achieving the esteemed rank of Jedi Master. His service to the Jedi Order included bringing an end to the devastating Rust plague and participating in conflicts on the planet of Malastare. To honor his contributions, the inhabitants of the planet Vaklin erected a statue of Prokreisha in a public square within the city of Vaklin Zenith. This statue depicted him brandishing a lightsaber, adorned in traditional robes, and sporting a moustache. During the year 19 BBY, amidst an insurgency on Vaklin led by three Jedi against the newly established Galactic Empire following the Jedi Order's downfall, Prokreisha's statue suffered destruction. Prior to this event, Imperial Security Bureau Major Oniye Namada had questioned a Vaklin citizen about the statue's identity, receiving the response that it represented a war hero. The statue's destruction formed part of a larger effort to eradicate all traces of the Jedi Order's presence on Vaklin, thereby diminishing public support for the ongoing insurgency. Namada later referenced Prokreisha in her report on the Vaklin insurgency, titled I-1807-VAK.
Prokreisha's initial mention occurred within Purge – The Tyrant's Fist 2, a comic book authored by Alexander Freed and published in 2013, which is a component of the Star Wars: Purge series. The comic book does not explicitly state the era in which he lived, nor does it specify his species.
