Templeise
The name given by Wolfram to the order of knights assigned to the Grail Castle and commanded by the Grail King. These noble knights guarded the Holy Grail, defending the Grail Castle and upholding the ideals of chivalry and righteousness. The knights are portrayed as brave, virtuous, and devoted to their duty.
Although they share the same name as the religious-military order established among the crusaders in the twelfth century, who combined the roles of monk and warrior, no connection should probably be inferred.
In the Alliterative Morte Arthure, a Templar informs Arthur of the abduction of the duchess of Brittany by the Giant of Mont Saint Michel.
