Plane of Ucalegon
The whirling, storming, chaotic maelstrom of Ucalegon was a dangerous, nigh-impossible plane to exist on. Volatile energies whirled about through its space, promising to pulverize or incinerate whatever was within in. The entirety of Ucalegon's matter and energy were emulated by subatomic nativus archons.
The Plane of Ucalegon's incredible power was harnessed by elementalists' magic.
A Primordial Chaos #
Ucalegon was a chaotic and unstable plane filled with fluctuating matter and energy. Things could randomly freeze or melt within the span of a few seconds. A person from Legere risked rapid disassembly when stepping into Ucalegon's plane.
Like all storms, Ucalegon held more calm "eyes" where existence was slightly more stable. Ucalegon's eyes were populated by populations of entities called Eidolons.
Eidolons #
An eidolon was an ethereal entity with a body only visible on the Plane of Ucalegon. They seemed to be multicoloured, flickering figures with white eyes. They swarmed curiously towards foreigners to Ucalegon, harmlessly reaching out to interact with things that weren't from their native plane.
Eidolons could be summoned to the material world in order to create elemental golems. A summoner would be greeted with gratitude from the eidolon, since being sent to the material world was an adventure and a treat. In exchange, the eidolon, in its elemental golem body, would obey the commands of the summoner (typically).
