Aeviternus is the god of immortal light. He was worshiped by Obscurians and Caelians before the birth of the new world, and is believed to be omnipresent, and credited with providing the ambient light throughout all of the early universe, even with the lack of any light source during the time. He is worshiped by peasants, nobles, and warriors. He is not heavily active, but his blessings are known to be incredibly powerful, and warriors wielding his light as weapon or armor have been nearly unstoppable on the battlefield.

Aeviternus is described as a humanoid figure, his face covered by a bright, radiant light emanating from it. He wields the light as weapon, and is generally depicted wearing robes, with armor of light emanating from them.
