I'm gonna toss a link to a zipped file containing all of the PCs and their biographies out into the ether. As they're 19th level, it's probably a good idea to release these ahead of time. Players who were around last time (keel tings? can't remember if anyone else was) get first dibs on having their character from last game.
The PCs should be attached. If not, I have a link I can send people.
For anyone not able to download the zip file immediately, here's a run-down of what's available. All characters are 19th level, and provided as is. I don't particularly feel like adding any unknowns to the mix, so no, you can't swap out powers. If something is REALLY weird with one of the characters, get a hold of me via the thread and let me know, or we'll work it out on the day of:
Ombert Starnhap, Halfling Fighter
Erdan Laethilar, Elf Cleric
Cedric "Dagger" Amontado, Human Thief
Quelenna Nimuriel, Eladrin Wizard
Saevel Moondown, Half-elf Warlock
Nemeia Tohlan, Tiefling Bard
