Prime Material Plane

Phlogistan

The Phlogistan is the vast explosive nothingness between places. It has its own flows and tides, which usually change too slowly to be noticed.

Only expert Spelljammer pilots can safely navigate the currents between the Crystal Spheres that dot it like jewels, each containing a sun and its attendant worlds.

Other Planes

Harn - Kèthîra

Harn on World Anvil

Harnwold's Sphere became destabilized after a high tech takeover forced mass evacuation. It broke away from the Phlogistan and gates no longer reach it. It may have fallen into another plane or dimension.

Many citizens of the Free Imperia, including the Emperor are refugees from Harn, thus it is an important cultural and linguistic part of The Free Imperia.

Sigil

Thought to be the center of the Planescape, Sigil is a city only entered by portals; it is adjacent to everywhere.

There is a portal to Sigil in the Great Pyramid in Nexus Prime.
