In the Books
When Finn fought his last battle in his Greencloak career, Donn went into passive state and never came out again. Finn is shown to still feel his presence, as Abeke sees him put his hand over Donn's tattoo. Finn's hair turned white and he got many tattoos to hide the fact Donn was a black wildcat; he then tried to save the bond at the Moon Tower. Near the end of the book, Donn comes out of dormant form to help with the battle for the Iron Boar tailsman, where Rumfuss states the bond was never lost. The Earl of Trunswick also mentions that he had tried to break Donn and Finn's troubled bond by putting Finn in the Howling House.
- "Donn" is an Irish name meaning either "brown" or "chief, noble"
