Lore:Overlays

An overlay is a massive field of mana that covers a large area and helps power spells and other magically powered abilities. They may be created by a mage school or other powerful entity. Overlays often have a substantial warping affect on the magical and metaphysical ecosystem in which they operate and can alter the rules that casting operates under. They may be so strong as to constitute being a world effect. The most common use of an overlay is for casters that have access to it to use its MP to help discount their spells.

In the Teriock game world, ECHO is the main overlay. It is intimately connected with not only magical effects, but primal and divine ones as well such as most holidays. Unlike most overlays in Roekron and other game worlds, ECHO is not thought to be created by any mage school or other organization and is instead believed to be an a more intrinsic feature of the world.
