Byrn Elgar is an enthusiastic and dedicated servant to House Ansilla. He was named Steward of Seawatch Castle and has never given up on this duty, even after the Castle was invaded and sacked by a Tuatha-led Bolgan army. He's remained in the castle the whole time, awaiting the return of the Master of the castle.
Byrn names the Fateless One the new Master of Seawatch in return for assistance in returning the castle to its full glory. While the Fateless One is away looking for the remaining staff Byrn works restlessly to tidy up the castle interior and open up collapsed passages. He brings in new furnishing and equipment, and beams with joy when each stage of the restoration is complete.
