I have 3 heroes. I want to do a Blackest Night / Champions Online Blood Moon type Event. I have 12 dead heroes to rise as "Zombies". I don't want to copy Blackest Night or Champions Online Blood Moon but I want to do something in the same spirt. Does anyone have any ideas on how they could be risen, should I have more than just undead heroes? I really need help with plot of this. I want to have the game progress over a several game sessions. What undead abilities should I add to the dead heroes?
When my game last left off, I had the heroes rescue the Mayor from the main villian and some villians working with him. The main villian escapes into a portal but before he goes extracts info from the Mayor. I haven't gone into detail what the info was, so I want to do something that.
