or, "My Character Died! Again!"
I'm going to be using slightly modified rules regarding coming back from the dead, as well as the introduction of new characters (whether run by current players or alternates.)
If your character dies at first level, there is no CON penalty when they are brought back; the character's XP is dropped back to 0 if you somehow have access to raise dead and the like at first level, or a new character with 0 XP is introduced.
At later levels, a dead character comes back one level lower than he was when he died, and with enough XP to put him halfway between his new and old levels. Alternately, a new character can be introduced in his stead -- still one level below, but with only just enough XP to have granted him that level. This is because a character designed at a higher level (especially with knowledge of what the party has been facing) will often prove to be more effective than one who has been developed "organically."
If a new player is introduced, his character will begin one level below the average of the active characters, and with enough XP to put him halfway to the next level.

Everyone's characters look to check out, so I'll try to get the introduction up shortly. Would you like a Rogues' Gallery as well?
