I was wondering if anyone filled out the Prince of Redhand by coming up with specific lines and stories for the hobgoblin and the fabler. Certainly there's a lot of room for creativity in what the hobgoblin brags about, and it would be funny if you sketched out how each skeleton dies in the macabre play.
Lots of characters are pretty thinly sketched out. I live near Hollywood and I have a friend who does improv comedy every week. He's not part of the group but maybe it would be cool for him to take over some of the characters.
I also have just opened the gates to Prince Zeech's feast right now and had the exact same idea about getting some of our local Vancouver Island improv guys in to help me with the guests at the party. Not sure if I'm going to be able to pull it off, but it really would spice up the role play and sew some seeds of loyalty to the place and its people. I think it would be pretty rich, particularly if we plant some key details that they could get from the dialogue, rumours that build PC trust for Lashonna and undercut her close ties to the despot Zeech for instance, or details that leave them thinking that an Alhaster without Zeech and his angels might be looking pretty good as a place to be, seeding some roots of friendship that may have been lost if all the party didn't get there all from Diamond Lake. Let's make this place worth saving from the Big Event! Let us know if you decide to do it!
