Overgrown broken mage tower (base)

Ruined ground storey of a mage tower: a round stone stump 14 m across, its 1 m wall broken off between 4.5 and 7.5 m, an arched doorway, a flagstone floor and fallen blocks round its foot. Its upper floors float above it as separate models (same origin) linked by floating steps. Mossy stone hung with vines, green-glowing rune rings.
