[@Jangel13], I'd like to be certain of a couple things, if possible.  Judging by your earlier statement about the troll's location and the possibility of Skrik noticing a change in the current I'm thinking that they would have to be upstream from Skrik's current location.  So, my question is this.  If he follows the river downstream, is he more likely to find a large body of water? A pond? A swamp? ... or a more dangerous area than he can safely handle alone right now.

Oh, and what season are we in?  Will we have to handle the challenges of the cycle of the seasons or is this going to be permanent summer for simplicity's sake?
