Trait idea: Pyromaniac

While burning a triffid grove to the ground with a flamethrower, I figured an idea for a trait: Pyromania. In other words, morale boost when near fire. It could be positive, or negative, and if negative it might include an “addiction” that includes a morale and focus penalty if the player hasn’t seen or started a fire for too long. Thoughts?

Been suggested a lot, haven’t found a good way to implement yet, or nobody has been willing to.
