Evil Campaign (5e) (Adult), anyone interested?
I can work around starting the campaign at a level 8 or 9 for the party. Strong enough to have fun but not to strong enough to make my head ache. A basic plot would be that the party will wake up in a cave surrounded by runes, ritualistic altars and even dead bodies surrounding them. You dont have past memories aside from your personality traits that you think you actually have.
You might have been summoned, created, or possibly kidnapped and experimented on. the party can ultimately go about and find out what really happened to them, why were they there, why they don't remember anything. But that doesn't mean everyone in the party are blank slates. I will let players have a background story, a past life, which will slowly in certain points in the campaign show up in visions or even unexpectedly as an example meet a previous friend/rival that recognizes during your travels.
One thing is certain though as each party members steps out from that cave, whoever gets in their way.. will pay.
I'll allow a lot in my campaign, freedom to go anywhere to explore anything, set up shop, conquer a castle, or whatever, as long as you guys pull it off.
