You saw a beacon shaped remarkably like the Holy Grail, the object of your quest.

Following it seemed only logical.

Now you've arrived at Castle Anthrax: an isolated castle inhabited entirely by young women, all of whom seem remarkably pleased to have an unexpected visitor.

They insist you're welcome.

Very welcome.

Zoot and her companions are unusually eager to offer their enthusiastic hospitality. Unfortunately, they seem considerably less interested in helping you continue your journey.

You came looking for the Grail, but the women of Castle Anthrax have other ideas about how you might spend your time—and increasingly creative reasons why you shouldn't leave just yet.

Maybe the Grail really is here.

Perhaps you should investigate thoroughly.

Besides, it would be terribly rude to leave so soon.

(If you somehow have gone this far in life without seeing Monty Python and the Holy Grail, correct that oversight. Today if possible. Or at least watch the Castle Anthrax scene on YouTube.)
