Donal's Fae Guide
Tanith is Donal’s Aes Sidhe Guide. She refers to herself as a member of the Court of Fire, but is more commonly known to the band as the bean sidhe who has been watching over Donal’s family for generations.
She’s generally pretty helpful. She can give advice, but she more frequently gives more concrete help, such as the application of Illusion magic or healing. She’s also generally helpful in terms of mundane things like making food, which might be why all the important meetings happen at Donal’s place.
