Sarkael

Sarkael is a daemon in a cave by the shore south of Cove in Ultima V: Lazarus.

He will tell the Avatar little about his role in the dreary cave, only stating he had been sent there against his will to spy on the citizens of Cove through his puppet Vortigyrn, but had been left with the ability to follow his own agenda. He had learned that the sisters Ava and Leona had discovered a secret which could be damaging to the Shadowlords, and he felt if he removed this threat he would be freed from Elistaria's control and could revel in the chaos and horror that the Shadowlords would soon unleash.

When the Avatar attempted to leave, Sarkael became hostile with the hero and attempted to kill the Avatar. Should Sarkael be defeated, Vortigyrn will be freed from the daemon's control.
