Honestly I actually think everyone is going to die. I just don't believe our characters have the skills or what I consider to be even more important, the knowledge of how the ghost works in the first place. Medje [i]could[/i] throw us a bone since it is the first official quest, but we did know it would be hard plus the reward also matches how difficult it should be. 

Seriously though, I myself don't see a way out of this short of just running away.
