Arciel


A Knight of the Round Table who killed his brother, Sanades, in combat for the love of a maiden. Arciel received a mortal wound in the fight.

As soon as he was aware of it, he tried to slay the maiden to keep any other man from having her, but she fled. Galahad found Arciel in his death throes and had him buried.
