High Magic is the greatest and most potent of all magics and its practitioners are the oldest and most mighty of all wizards in the Warhammer World. The most noted High Mages are the High Elves of Ulthuan, whose ancestors travelled to the Old World and taught the rudiments of sorcery to the savage humans that lived there. High Elven Mages can use High Magic, but they can also use Battle Magic.

Apart from the High Elves, High Magic is also known to the great Slann Mage Priests of Lustria, the progenitors of sorcery, whose secret knowledge plumbs depths unimaginable to even the mighty Elf Mages of Ulthuan.

High Magic is the highest and most noble form of
sorcery. Its practitioners draw upon the purest and most potent power. As they cast spells they bring the winds of magic into harmony, and draw away the destructive and evil aspects of magical power. A High Mage's mind is attuned towards this vital source, and against the corruption of Dark Magic. Dark Magic is the opposite of High Magic, and the two are implacable enemies, the one virtuous and the other corrupt and evil.
