blue flame

Exploration Stage: Burned-out Estate
From: Harper McGill
Description: You may be a logical person, but sometimes you can't judge things by appearances. While investigating the cause of the fire, I found a letter in my mailbox that was burning with a strange flame. See. Because you'll see that arson may not be the only cause of the fire.
Completed: See, the letter is burning with blue flames. But it is not burnt! I examined the letter. It is a normal letter addressed to Eli. Letters, photos, drawings. Nothing interesting. It must have been set on fire by some unknown force.
