Ack, this is what I get for going to sleep earlier than usual.
Zurai,
Shayuri,
Nac Mac Feegle: Thanks for the concepts (and thanks to Zurai for the rules clarifications, too)!
Scurry: I don't have Unearthed Arcana, but if you want to post the basics of the Human Paragon class in a spoiler block, I'll take a look at it and let you know if it's kosher.
Ambrus: I'll let you in as the last one to submit a character concept, since you've done so much for the modern Planescape community.
I'll answer your question about the selction process just below.
All: Thanks to everyone for your interest and time! I think I'll close recruiting for now, with Ambrus as the last potential player. Character selection will be primarily based on whom I think would fit nicely into the background material and with other members of the party. Since I'm planning on taking a maximum of six players at this time, I'll unfortunately have to leave so of you behind, but take heart! If one of the current players bows out or meets an untimely end, you'll take priority as the ones to step in.
I'll look through all of the submitted concepts today, as well as take care of those of you with pending questions or concerns. I'll let you know of my selections by mid-afternoon Pacific Standard Time (GMT -8 hours). Thanks again to all!
