A fantasy world

As you close the door behind you, it disappears, and you realize that you've been abandoned wearing only your camisole and cotton shorts, on top of a hill, somewhere you don't recognize at all!

Down the hill you can see a paved road, leading to a town in the distance, but no one on the road seems to be human! You double take, and then after a moment, realize that what you can see are centaurs straight out of children's storybooks, witches and wizards in robes and half human, half animal creatures, amongst others!

You're stuck; you need to find out what's going on, but you should also avoid meeting anyone, or anything, that you don't want to have sex with!
