Zealor

"It helps to think of the mind as a three dimensional plane. The first dimension, emotion, lays the very rudimentary groundwork for the instincts of the mind. The Second dimension, willpower, helps to manage the effectiveness of emotional impulses on the mind. The third dimension, knowledge, helps to create rational thought in addition to the other two dimensions, and keeps them in check. If just one dimension of the plane is absent, the mind cannot function. Yet, in this world... there are those that do. The mind is a powerful thing, defenders. Sentience is a gift when used correctly, but it can also be an unshakable curse if used incorrectly. Zealor could be destroyed by one unhinged mind. While I assumed the most likely candidate to fulfill this goal was destroyed millennia ago, I was mistaken." -  Pelios, Benefactor of Zeal
