First, I'm VERY excited about this game! Good group of players, good GM, good adventure . . . this is gonna be cool!
I got my copy of the new Inner Sea World Guide in. I've got ideas for Halal's background, but I wanted to wait for the World Guide to see what it has about Ustalav so I can sprinkle a few details in there.
Firvi and Halal have the same campaign trait (Chance Savior) which is gained by happening to be at the right place and time to rescue the Professor from certain death. We've talked about having both of us be there to save him in the same encounter, which would create a small link for our characters but not anything that would give us knowledge of each other - just that we'd seen each other before. perrinmiller's already got his version of the encounter in his background - I'll work my version into his so he won't have to edit.
I might build a little stronger connection to the Professor into my history as well - with the Inquisitor's thirst for knowledge of his foes and Pharasma's hatred of the Undead it should be easy enough to get a natural connection between the Professor and Halal.
Not sure you noticed, but I changed Halal's alignment from TN to NG. Neutral & Chaotic Good are by far my favorite alignments to play, and with a game that promises to last as long as this one I want to be happy with my character.
The school system in which I work is on Spring Break this week, so I should have plenty of time to kick things off!
Miscellaneous Notes: I'm glad you decided to run it 'as is.' The Trust factor seems really cool as well - interested to see how that turns out.
