Here's a question for you!
What happens if a party member gains the Fear (x) trait, somehow (say, by one of the mutations).
Does this mean he causes Fear (x) only to his enemies (as he would be a dreadful adversary), or does he cause Fear (x) to his party and friends and allies too (perhaps he is just a dreadful manifestation of the warp)?
How do you go about handling Fear and your party, in the case where your character has the fear trait?
