Fictional character biography
One thousand years ago, Sir Lancelot succeeded in the quest to find the Holy Grail and ascended, as does Sir Galahad. After an initial failure Sir Percival is able to discover the Grail, Merlin then appears before Percival, asks him to guard the mystic prison in Hell that he had created for all the evil creatures in England at King Arthur's request. Merlin sent Percival into the Region Beyond, where his purity manifested as the Golden Knight. Etrigan the Demon fights the Golden Knight in order to gain passage into the prison. The Golden Knight eternally guards a gateway which leads from England to Hell's Region Beyond (possibly the Infernal Province known as the Labyrinth). Etrigan leaves his brother Lord Scapegoat a resident of the prison, stranded in the Region Beyond, and escapes with a mystical scroll from the Thing-that-cannot-die.
