A dying prisoner who needed witnesses for his final truths — and used them to confess to the assassination that started the war.
// ON RECORD
Personnel
Prisoners
A boy of maybe thirteen, with ears that stick out, new to The Rock and scared out of his mind.
KorlokFour-armed self-proclaimed captain of the Rust Tide Pirates. Nobody knows if the title is real. Everybody knows he's a grade-A asshole.
A hulking tabaxi in a shirt several sizes too small, who claims to know the back ways out.
An east-wing prisoner and a source of the block's more elaborate rumors.
OotThe oldest living prisoner on The Rock, and the man you go to when you need to know something.
Guards
A guard of maybe twenty who locked himself in the guard tower and cried, with his thumb near the button that floods the block with riot glass.
A cruel, heavyset guard the party found being beaten to death in the library, and left there.
Outsiders
The bystander 
ND-E killed on a job. The reason he is on The Rock.
The last Emperor of the Third Imperium. His murder emptied the Iridium Throne and started ten years of succession war.
Nothing on record matches those filters.
