Nothing is known of Bedwyr's early life, though he probably spent it in Lleuenydd.
Bedwyr spent most if not all of his early adulthood as a member of Gwrwst's teulu, becoming a captain and in time the champion of the hall. As the former he has many times led Gwrwst's men on successful raids and proven himself in battle. As the latter, he has proven himself highly resourceful.
When Arthur massacred Gwrwst's war-band, Bedwyr was the only survivor. He did lose his right arm during the fight and in the days following.
Bedwyr is currently a member of Arthur's teulu.
Bedwyr is a man of honor and integrity. He knows of no higher dishonor than to lose his king in battle, and no greater duty than to serve an honorable king. Bedwyr had grown disappointed in Gwrwst even before he learned how he met death, but now in Arthur he feels he has found a worthy man. He loves his wife and is devoted to her.
