Agamenor

Ganemor

A Knight of the Round Table and companion of Arpian of the Narrow Mountain and Amatin the Good Jouster. The trio hated any knights of Lancelot’s family, and they consequently attacked Acorant the Agile and Danubre the Brave, two of Lancelot’s kinsmen, during the Grail Quest.

Agamenor and Danubre were the last two survivors of the bloody brawl, and they killed each other.
