Xol greatly disliked evil and did all in his ability to stop it. He was adamantine in his crusade and often persuaded his mate to join him.
In 1491 DR, Xol noticed a group of troglodytes moving into Mulmaster's sewers. He convinced Laal to follow them in order to warn others about this menace. Following the troglodytes, Xol located the mind of a particularly evil human. Xol tried to follow this man but was killed in an ambush. His body fell into the sewers and ended up on surface where it was discovered by some children.
