A new story is frequently being whispered in the dark corners of taverns across the country, telling of a traveler that occasionally appears in quiet, rural towns; that draws with him a plague worse than any other: a dragon's wrath.
Ã¢??IÃ¢??m not telling that story againÃ¢?Â the bard protested, leaning on the hearth of the inn with his arms crossed in defiance Ã¢??everyone has heard it over and overÃ¢?Â¦why not something else?Ã¢?Â
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.
