Arthur

King Arthur is the leader of a Paladin expedition in Fallout 2.

Background
This particularly odd fellow is leading a band of noble knights on a most holy quest. The Holy Hand Grenade of Antioch cannot fall into the hands of wrongdoers, as it's the moral thing to do. Really.

Other interactions

 * Arthur will claim that he and his entourage have a GECK, but won't give it to the Chosen One. He'll just pay the Chosen One $309 for pointing them to the Grenade (a random direction suffices).

Behind the scenes
Arthur is an overt reference to Graham Chapman's Arthur from Monty Python and the Holy Grail, who was, in turn, based on King Arthur.

Appearances
Arthur appears only in Fallout 2.
