Game concept
Intimidated
From the game's encyclopedia
Characters who greatly fear another character are Intimidated by them. This is usually caused by Dread and/or a cowardly personality.
Intimidated characters are less likely to initiate hostile actions against the character they fear, including joining or starting Factions.
Characters who are even more fearful are marked as Terrified.
