Chevaliers Moins Prisiés
The lowest of Arthur’s knightly orders, composed of old, weak, ill, cowardly, or inexperienced knights who did not seek adventures. A rank above the Table of Less-Valued Knights was the Table of Errant Companions.
Perceval was originally a Less-Valued Knight before he was more properly seated at the Round Table.
