Plane of Ghostly Ferrous Lava
My humble attempt at using the Ionian Ontology generator from Liche’s Libram blog as an inspiration for a plane of existence.
Based on this prompt:
This world is an expanse, mostly void, with 3 dimensions organized into a sphere with a single point which is the "center" or "bottom" of the universe. There are three elements: magma, iron, and ectoplasm, which settle in concentric shells around the center in that order. The elements can spontaneously transmute according to the order:
magma → iron → ectoplasm
Small but regular amounts of magma are spontaneously generated in vacuum conditions. The more intelligent entities are observing something, the faster things get.
This plane consists of 6 concentric spherical layers:
Upper ferrous layer.
Intermediate magmatic ocean.
Lower ferrous layer.
