The ruined city of Oldport, destroyed nearly 200 years ago during a violent raid from the sea. During the day, a desolated skeleton of what once a thriving port city. During the night, magical splendor causes the city to regain its former glory and the dead rise to continue their lives.
The ruin that birthed a society; the Life and Times of a city in the throes of death.
11 great statues of lost gods being chipped away by the condemned.
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.
