In Session1 we introduced the original four players (Aeso, Will, Dylan, and Dillon). As they arrive at Tartarus station they receive a lecture that informs them no one has escaped before. This introduces them to Davak, the Kalgeros warden. Within the first few hours in prison Lacerta starts trouble by attack a cellmate who was bullying Ximeon out of his bunk.
This violent altercation resulted in the entire cellblock being put into "administrative segregation", a fancy word for the hole. It was there that The Voice first contacted the party. They were instructed on how to escape and where there would be a ship waiting for them.
