Colin O'Hara is an Irish General.
Before Seven Ancient WondersEdit
General Colin O'Hara was the main representative of Ireland when seven nations came together to arrange a mission to restore the Golden Capstone and protect the girl, Lily, who could translate the inscriptions leading to the Piece's locations. O'Hara decided to dispatch Zoe and Liam Kissane from the Sciathan Fhianoglach an Arim to represent Ireland in the mission.
After the success of the mission, O'Hara was at the following meeting of nations to discuss what to do next.
After Seven Ancient WondersEdit
O'Hara would on occassion debrief Zoe on the post-mission details. He became something of a grandfather figure to Lily, who would sometimes come along with Zoe. However when he died of a heart attack, Cieran Kincaid took his place. (The Five Greatest Warriors)
