In most versions of the quest for the Holy Grail, Gawain is the most important supporting character. In De Troyes's and von Eschenbach's narratives, Gawain sets off on another quest at the same time that Perceval decides to pursue the grail, and their narratives parallel each other. In this sense, Gawain is a foil to Perceval. In the First Continuation and The High Book of the Grail, Gawain actually manages to come to the Grail Castle but fails where Perceval later succeeds. In Malory's version, Gawain remains outside the chosen circle of grail knights because of his human failings.
