Warrens of Magic
Warren Magic is the most common way of invoking magic on Aerth, although it is not the only way.
To cast a spell a caster must open himself to a warren of magic essentially opening a portal to a extra-dimensional space and draw energy from within it. As a caster gains better mastery of a warren he is able to draw more and more power. However Exposure to the mystical energy can cause corruption both mental and physical to the caster over extended periods of time, so the ability to draw upon the energy comes at a cost.
Here is a list of Warrens and some detail on what powers the contain.

Access to this warren allows treatment of injuries and diseases More accomplished casters can access High Denul, which can be used to perform more complex healing procedures like regrowing limbs, and rituals that can slow or stop aging.
