Mroon Jassa was a Human Jedi Master who established the Jedi Praxeum on Truuine. Over the course of nearly a year, Kith Kark thrice came to Truuine and asked Jassa to train him, but the first two times only as a hobby or a task, meeting with refusal from Jassa. Only the third time, when Kark felt the Force and sought to obey it, did Jassa agree.
During Kith`s time at the compound, Mroon Jassa was unexpectedly called away for an indefinite period of time. Unfortunately, it is unknown what happened to Master Jassa on this trip.
