His hunger sated, Parzival was conducted to luxurious sleeping apartments, but, when he was ready to leave on the morrow, all the castle seemed deserted, and it was only when he had crossed the drawbridge and it had been raised behind him, that a harsh voice was heard vehemently cursing him.

Shortly after, on learning that a sympathetic inquiry would have dispelled the gloom in the palace, he had just left, Parzival attempted to return, but the mysterious castle was no longer to be found.

Such was our hero's remorse for his sin of omission that he continued the quest for years, doing meanwhile all manner of noble and heroic deeds.

In reward, he was knighted by Arthur himself, and bidden by Merlin occupy "the Siege Perilous" where his name suddenly appeared in letters of gold.
Our version of the story explains that, just as he was about to sit down in the Siege Perilous, the witch Kundrie arrived, and hotly denounced him as an unfeeling wretch, a sufficient reminder to make Parzival immediately renew his quest.

Adequate penance having been done at last, and the young knight having stood every test without losing his purity, Parzival was finally allowed to atone for his unconscious fault.
