Infragercia

Beneath the surface of Aemaphia lie the strange realm known as Infragercia. The Infragercia, better known to adventurers as the Underlands, sprawl under Aemaphia as a vast labyrinth of glowing caverns, underground seas, and forgotten ruins. The uppermost layer, the Infragercian Shallows is a cold, desolate realm of shadowed tunnels and sparse life, where silence reigns, the air is often stagnant, and only the hardiest creatures and fungi cling to existence. Far below, the Infragercian Expanse is filled with bioluminescent forests, ancient antediluvian relics, and creatures both wondrous and terrifying. Farther still into the depths of Aemaphia is the Infragercian Abyss, a place of unimaginable danger and incomprehensible mystery, where reality itself seems to shift the deeper one ventures. Here, legends hold, the Tarrasque slumbers between rampages and diamonds the size of mountains glistening from some fire even deeper below.
