Prism riot

A prison riot on the Jedi prison Prism occurred in 19 BBY, shortly after Darth Vader, alongside Moff Trachta and Laurita Tohm's arrival at the facility to cure an ailing Emperor Palpatine from the effects of Aorth-6 as a result of a military coup orchestrated by Headmaster Gentis. Tohm had requested that Darth Vader try to recruit several inmates within the prison, but they couldn't do so before the riot broke out, forcing Vader, Trachta, and Tohm to fight them off. During this time, Tohm discovered an inner darkness and power that he never thought he had.
