jmarshallmorgan: So somehow i accidentally went down in the dump passage before i was ready and now, I've lost my previous saves. So i'm down in the dumps (metaphorically and literally). How screwed am I? is there any way back up? There are 1 billion guards in the prison and i wasn't ready to do all that. Blah!
You cannot go back. Sorry.
As to the guards, you can go back to the Hermit in the tunnels and rest there if you need to heal and restock your spells. More importantly, if you have a thief, you can really put their Hide skill to work by having them scout the area ahead in order to get an idea of what you are up against and help you plan your attack.
