Clairasyl is loyal to Belrain's cause. He understands the precociousness of gnat-lived humans but only tolerates it to a certain extent. He mourns the death of his brother, Oxyclean, whose blood and viscera were drunk by a flock of demon birds during the assault on Bargle's castle. Clairasyl believes that he masterminded the attack.
