Eledryll - Planar Palace

It was in the astral plane, amidst twinkling stars and rushing comets, that the great astromancer made their home. There, the great, towering building floats in the ether, like a black stone scar on the face of the void. The interior was a marvel of both arcane and engineering, with scores of rooms dedicated to all manners of studies, a lavish foyer and sprawling library. Though well hidden, the planar palace was eventually discovered by...rival entities. It is truly a shame that you were there when these otherworldly forces came to invade!
