You can expect characters to die, but ultimately I'll leave it to you whether or not you survive the event. I have plot ideas for the survivors as well as player's new characters (if theirs died). And reasonably speaking, although I would like this RP to go on for years, I think I would be more inclined to end the RP at that point and create a sequel RP to give new players a chance to join and keep it fresh. But I'm still unsure and open to suggestions :)
