Fiction:The Firmament/Infinite Abode

The Infinite Abode is the demiplane controlled by Infinitum, the goddess of magic, which floats through the Ethereal Plane.

Description
The realm of the Mother of Magic is described as a particularly strange place where all objects, including the ground, are made of the same shade-like substance as Infinitum herself. The goddess' curious nature leads her to allow mortal visitors into the realm provided they can find it, though she is quick to kick them out if they attempt to overstay their welcome.

This realm is ambulatory in nature and rarely stays in the same place for long, for Infinitum is always travelling.

Inhabitants
The Abode is home to creatures who resemble normal animals, but who are in fact silhouettes decorated with stars, much like Infinitum herself. These strange creatures appear to behave like their common counterparts and generally ignore visitors.
