I'm so sorry Derissa's been... non-existent. I'll try to be more active in Scene 2... hopefully life's calmed by then...
Derissa has a private objective and an unfortunate situation that requires her to help...well, I guess she could let the party wander off on their own, track them and steal their treasure, but what fun's that? So, she'll go with the party as long as it's toward fighting and accomplishing her goal.
They can always go back to Artesia... >.>
