Planescape - Strays!
A tower in the far Outlands where seasons change irregularly and frequently, established as a beachhead by the eladrin to research this phenomena. It is located on a tropical island surrounded by mangroves, in the middle of a vast ocean.
The tower is constructed of a unknown metal and is mostly rooms of vegetation connected by narrow corridors.
Lacking an easy means of returning to the Feywild, it is largely self-sufficient, but occasionally trades with Omen when the city slides into a position near the tower.
Within the last three days, it was invaded by slow men.
