The only character guidelines are this:
• Level 4
• Allowed books include the core books only
• Don't bother with any equipment or weapons, since those will be supplied later
• If you make a spellcaster, keep in mind that all spell components will be supplied to you, so you can choose your spells freely with that in mind
• Your character can be good or evil, it's up to you. There's a bit of a moral dilemma here for good characters, considering that to gain your freedom faster, you have to really do a number on your opponent. That, however, is your problem.
Anyone who wants to play, go ahead and make up a sheet and send it to me directly in PM (so others can't see what you can do). For your character background, give a few paragraphs about the character's career so far. Being 4th level, they've been around the block a few times, and maybe have just started making a name for themselves. You can also include a paragraph about how you were abducted. Generally, Kiraxis has agents who scope out new "talent," and then abduct them usually through brute force, such as clubbing over the head and dragging them away, or drugging them. After being abducted, you wake up in a cell, which is where things will start off in the game.
Also, keep in mind, that if you like the game and get killed off, you can always whip up another character and get abducted all over again.
