Fenian Cycle
Goll mac Morna (or Goal mac Morn) was a member of the fianna and an uneasy ally of Fionn mac Cumhail in the Fenian Cycle of Irish mythology. He had killed Fionn's father, Cumhal, and taken over the leadership of the fianna, but when Fionn grew up and proved his worth Goll willingly stepped aside in his favour.
