The Full Goblet is a modest-sized, working-class tavern (public house), run by Hilgar. Hilgar is a bit over the hill and shabby, as is the general establishment. However, good solid fare at a decent value, and a regular and noisy clientele, keep the place in business, and the bar is also well-situated to bring in travellers.
In the middle of an unimportant combat with some bandits a burst of wild magic transforms all of the PCs and their opponents in to random animals and monsters. They retain their intelligence (though not, of course, the ability of speech). They can either carry on the combat in their new forms, panic, or otherwise react how they see best. After about an hour, they return, unharmed, to their normal form.
