Their art was moved to Eyrie in the second edition, and once the second GryphIns Boxed Set released, Merin and Silver art were added. In the original, Rybalt was labelled as Bane of the Crackling Sea Reeve, while Zeph and Kia, both with the Reevesbane epithet, were listed as the Bane of the Redwood Valley Reeve.
