Moonlit Tower

The Moonlit Tower was a mysterious tower situated on a crag northwest of the town of Maerstar.

It only appeared when the moon was full and its rays illuminated the crag. Then there would appear a small and slender tower, glowing blue-gray as though it were constructed of tangible moonlight. Adventurers were able to enter the tower and describe the interior. Inside, there were seven rooms and a rooftop floor. These were connected by a spiral stair of stone treads that floated without any visible means of support, and with no rail either. Magic spells cast within the Tower had unusual effects.

There were many different tales about was found within. At times, the Tower was either empty or inhabited by rare or bizarre monsters; for example, an argos, or beholders, steel shadows, watchghosts, and strange, unknown creatures. Sometimes there was treasure, sometimes there was not. On occasion, explorers returned with disease, eggs that hatched into dangerous monsters, or statuettes that reverted to reverted to living monsters.

Sages theorized that when not on the crag the Moonlit Tower traveled between several other planes or even to other worlds. When it disappeared, any explorers still inside were rarely seen again.
