Sanity

Sanity measures a character's psychological anchor to reality and their humanity.

Starting Value: 10 Boxes

When encountering a traumatic event, a character rolls Resist Erosion with Memory or Willpower (player's choice, based on how they fight back in the fiction). Failing this roll permanently erodes a Sanity box. As the boxes empty, characters slide into severe madness: social penalties, derangements, and debilitating apathy. At 0 Sanity, they become a mindless "Hollow."
