Geomancer

A geomancer is a mystic who draws power from the living earth, channeling stone, soil, and ley lines as easily as others wield fire or steel. They read the whispers of shifting tectonic plates and the subtle flow of underground rivers, seeing patterns in nature that guide their magic. Often clad in earthen tones and carrying crystals or carved runes, a geomancer can summon walls of stone, shape terrain to confound enemies, and call tremors that shake the battlefield. Beyond raw might, they serve as guardians of balance, interpreters of the land’s will, and shepherds of the primal forces that sleep beneath the surface of the world.
