haha I hadn't thought about that. Everyone starts as a living human (faction), as you die (permadeath) you are turned into a zombie (opposite faction).
But I think if you are killed as a zombie, that should also be permadeath.. aka reroll a new toon. It's the only way I can see there being a real element of danger. I think of it like poker, I don't care about it as much as when there is money on the table.
