The Inner Plane of Earth

The Inner Plane of Earth is a vast stone-world of weight and memory, a finite elemental planet where pressure, depth, and endurance govern all existence. Appearing as a colossal rock sphere embedded within the Elemental Belt, it is a realm of layered crusts, endless caverns, and a dense, ancient core toward which all things descend. Here, reality is shaped not by motion or flame, but by mass, compression, and the slow authority of time. No horizon defines it, only deeper strata, and no traveler reaches its center without surrendering to the planet’s immense will.

Within this monumental world lies both creation and collapse. The Plane of Earth is the source of all mountains, metals, caverns, and foundations across the multiverse. Life endures in forms shaped by pressure and patience: earth elementals, colossal burrowers, crystal-bound civilizations, and beings born of stone and silence. Cities are carved rather than built, histories are etched into bedrock, and the past lingers not as ruins, but as memory held within the land itself. Earth preserves all things, yet grinds them down in time.

This sourcebook descends into the depths of the Inner Plane of Earth, unveiling its realms, powers, and primordial tensions:

Thar-Gael

The surface realm of towering mountain ranges, crystal deserts, and stonebound civilizations, where the Oreads have raised enduring cities upon the living crust of the elemental planet.

Morhûn

The fractured depths where stone rebels against itself, fault-lines roam, and chaos festers beneath unbearable pressure. Here, Kerubi’s influence warps caverns into unstable labyrinths of collapse and impulse.

Ur-Gwen

The deepest and most ancient core-realm, a domain of perfect compression and primordial stability where Gwenna, the Primordial Land, endures as the unshakable foundation of all that exists.

Origins of the Plane of Earth

Born during the Sundering of Unity, Earth condensed into permanence. From its depths arose Gwenna, whose patience shaped worlds, and later Kerubi, whose disruption fractured the plane into eternal tension.

Elemental Powers and Factions

Oread civilizations, geomantic orders, mining consortia, stonewardens, and cults of fracture struggle to preserve, exploit, or unravel the foundations of a plane where change is slow, but absolute.

Within these depths lie stories of endurance, memory, collapse, and resolve.
Here, adventurers descend through living stone, confront gods of stability and chaos, and learn that in the Plane of Earth, what endures defines what matters.
