A valley in which rested a castle, guarded by a lion, and ruled by a heathen lord who never let any Christian man leave the valley alive.
Peredur came upon the valley during his adventures, killed the lion, and defeated the lord’s warriors in combat, killing two of the heathen lord’s sons.
The lord eventually surrendered to Peredur, and Peredur sent him to Arthur for penance.
