Some creatures are able to exist solely by syphoning magic from the High Realm. Others, such as me, are not so fortunate. We must balance our magical link to the High Realm with magic filtered through the Earth. If we don't, the magic of the High Realm will overtake and devour us: thus, the necessity of wizardkind. Wizardkind are vessels of diluted magic, and with no link to additional magic, they are limited in their potential.
