Asil is a werewolf in the Marrok's Pack. An old wolf, he is known as the Moor. Formerly mated to an Omega wolf, Asil was sent to Bran by his son to be put down. For reasons unknown, Bran hasn't.

Asil is, despite his age and instability, one of Bran's more trusted wolves. As such, he was sent to the Tri-Cities to protect Mercy when the Columbia Basin Pack was captured.

Asil grows roses and has spent years breeding them. It is considered a rare honor for him to cut and give away any of his roses.

At one point he was hunted by Zee, who mentions he got away cleanly.
