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.
A cave with weapons sunken into the walls, blades sticking out of the floor and ceiling, and so on. Possibly, any weapon used in it could be torn out of the hand and sink into the stone.
