So, let's see here...
We've got a deceased and now rezzed Evil Warrior who is now even more Evil than before, given the ability of flight and several other insane bonuses, and has immense power over the undead, and evil in general. This warrior happens to serve the God of War, who became a god by killing his predecessor. He mysteriously travels with a dog, the only creature he has not yet tried to kill/expressed an interest in killing. He is a murderous fiend; he would, and has in fact tried to kill his companions for the DnD equivalent of a Klondike bar. He is also confusingly genre-savvy, yet also a total imbecile who will most likely kill quest-giving NPCs, only to strike up a conversation with the next random encounter he sees. Hates trees.
Then we've got a gnome rogue, who is now part tree; he enjoys jumping and tumbling around enemies and generally being no help whatsoever now that we've got a second rogue.
There's the self-centered and self-righteous wizard who has a history of being the most competent party member while at the same time doing absolutely nothing. Missed becoming part tree, however.
Then we've got a rogue/wizard with a disturbing extraplanar cat, whose interests primarily involve exposition that belongs in a single player campaign, unlocking things, and inflicting elemental pain on himself. Is currently sharing custody of a dagger with the other rogue.
And then, of course, are the two most developed characters in the campaign: Donkius Titanius and his clone, whose antics are so demented that their very presence determines whether a session shall be gritty and serious or laugh-out-loud hilarity.
(I am in no way attempting to be biased here; these are all the character traits I know of for each character; Deadris simply has a larger description because I know more about him since he's my character.)
