I am prepping to run Carrion Crown and after reading Wake of the Watcher, I was considering trying to get one of my PCs to (unknowingly) be the grandchild of Manus Undiomede.
The PC would recall his grandfather Manus (not using the Undiomede last name) telling crazy stories of old cults and ancients as he grew older and more senile, and would remember him being overly protective of everyone, but especially the girls of the family. He would have had a strange fascination with dream interpretation and warding rituals as well. All of this would give the PC a +2 bonus on checks related to the old gods and the old cults.
I would also rule a Sanity check would be needed by the PC when they find the portraits, and they see that the PC looks identical to the men in the paintings, then of course sees the painting labeled Manus Undiomede.
I have also toyed with (if we have any changling pc's) perhaps making them a child of Oothi... but have to flesh that out more.
I think it will be fun to have the PC tied in this way, but really have nothing come of the background for the first few adventures, to where they will probably not really think about it until boom!!!! it hits.
Any tips or suggestions to bring this along more? I would appreciate any advice or suggestions.
I am also trying to think of ways to maybe have the Sanity mechanic in the earlier adventures to some extent... but I do not know if they are horrifying enough (though the skin-changer could be pretty bad).
