You refuse, but she joins you!

"No thanks. I'm not interested in foot slaves yet. In fact, I'm currently on a quest to make myself stinky enough to be raised up to the status of a seventh Stink Queen!" You boldly proclaim, and the Sphinx seems a bit surprised.

"Well, in that case you'll want to go and raid one of the nearby pyramids! You'll be able to find many magical artifacts that will make you into a stinky goddess! However, it's rather dangerous, and you could end up a foot ****... Which is why I'll help you!"

You stare shocked at the Sphinx and her declaration, and before you can say anything she starts walking off, and your horse follows her.
