@ihinkaOh yeah I'm putting an FAQ together for things like that, I'll have it up soon :D
If a character dies and is reborn, will he be reborn with a different appearance/name/traits and the like?
That is entirely up to the player.
The god form will almost never change. Players can adapt their mortal forms between incarnations if they so wish. If you like a particular incarnation alot, you can keep as many details and tide them over as appropriate.
Obviously, there will need to be tweaking in between incarnations to bios.
You can of course switch genders and age and stuff as you see fit, but it's entirely up to the player what they want to play.
@Leos Klien yes Dark Gods are very much a faction to play!! We'll need a few bad guys in the mix ;D
