Publisher's blurb:
Sanity rules in SagaBorn attempt to simulate the inner workings of a character’s mind as they deal with the strange world of Atheles.
There are two reasons we think this is an important addition to the SagaBorn core game. First is to illustrate the difficulties in the characters' minds of the characters as they encounter with the bizarre and often terrible things happening around them. The first time the undead rise up to fight might be a mind-numbing event, not just a combat encounter. Or, opening and reading a Grim Mortis warps the character's perspective of the universe. Thus, keeping track of sanity becomes a scale trying to balance a sane mind amidst the horrors that Atheles contains.
The second is to add consequences to overt violence. We don't have alignments in SagaBorn, but acts of unwarranted violence are considered evil. When one commits these acts, they erode the barriers that separate them them from being more than brutish animals. In a tabletop game where we are simplifying a complex world into a world built on numeric formulas, these rules will allow players to have their characters deal with the loss of compassion and understanding.
