Cerberus

About
A canine duendy birthed by Macha, much in the same way Deirdre created her. Macha created him to help Shura get to her as she was locked in place. He attacks much like a dog would.

He assists Shura in the fights with Fomoire and Illusionist. His only task is to guide him to Macha, whatever the cost.

After the battle with Illusionist, he says his goodbyes and then fades away. Seemingly satisfied that his job has been completed.
