Lieutenant Scarle was a lieutenant of the guard of the Hand Brotherhood. He was ordered by Captain Regalio to stay out of the Tower of Fire. Unfortunately, he did not listen, and was killed by the fire and lava within the tower.
This was not the end of Scarle's Service however, as Archmage Kahmin Ramin requested that Adept Al-Hayr bring the charred body to the laboratories as they could make good use of it[1]
