My character wasn't captured and imprisoned as a shadow. He rose as an undead only after dying in the prison; a process the other prisoners are likely aware of since his death was slow and agonizing. He hasn't yet attempted escape because, until just before the campaign starts, he was still clinging to life.Ambrus: Yeah, you're probably being held by force, if they know what you are - not too difficult a task for a cabal of wizards.
