@Kipi, what's your story about basically? And no-one say I'm not encouraging people to spam...
Okay, this is the original idea, and it was made for singleplayer game, but with little modding it can be fitted as party game
SO, there was main character, I called it X. One day X suddenly wakes up, noticing that he is in temple where he is treated by several clerics. He doesn't remember anything, and I mean ANYTHING. Or, he does, his only memory is face of somekind of demon. Clerics says that X was founded in field just bit shout from the town. The town is small town (don't have the name yet). After few days X gets out from temple, and starts to find out what has happened to him, who he was, and most iportantly, what is the demone which face he can remember and what does it have to do with anything.
So, the story can be modded so that after getting out from Temple, X finds his way to local inn where he meets PCs and hires them to help him. The X joins the party as NPC, controlled by DM.
