Seems like a strong show of support for the abyssals. *smiles* And it's something I could work with, if you people are interested. If there's not major opposition from certain quarters, I would be willing to run an Abyssals game.
All of your characters will have to begin as a circle under the First and Forsaken Lion, though you can also take the Black Heron as a leige if you're feeling feisty. The group will be given horrific objectives by the Lion, sent out into creation, and then recalled back to the Deathlord's citadel to report on their progress. A major theme of the game will be finding ways to sabotage the Lion, or come up with ways of breaking creation even WORSE than what the Deathlord envisioned.
PC on PC conflict is very probable, so I do reccomend picking up mental perfect defenses unless you want to get bullied into things by your companions.
Character creation will use the normal rules in Manual of Exalted Power: Abyssals, except that characters automatically get a single perfect defense charm for free, plus all prerequisite charms, provided they meet the minimum essence and ability requirements. Valid charms to get through this method include: Death Deflecting Technique (in melee), Wounds Mean Nothing (in resistance), or Flickering Wisp Technique (in dodge). Only Abyssal or Solar charms are valid for your free perfect defense charm, though getting access to solar charms would stretch the limits of a starting character.
Another house rule which may affect your starting decisions is that health will be calculated differently from normal Exalted chronicles. Characters get a number of -1 and -2 health levels equal to their stamina, and for each point by which a character's essence exceeds 1, the character gets an additional -2 and two -4 health levels. Abyssals are champions of death, and they are HARD to kill.
Note that it is still valid to pick up deathlords other than the First and Forsaken Lion as mentors, if you so choose.
