CHAOS!

CHAOS:

Chaos is a powerful and unpredictable energy that can chaorrupt (short for "chaos corrupt") objects and beings. It is a recurring theme of AQ Worlds and controlled by Drakath and his 13 Lords of Chaos. Lords of Chaos try to summon the Chaos Beasts (Based on beasts from mythology, such as the Hydra, from Greek Mythology, and the Roc from Arabian Mythology).
As always, the opposite of Chaos is, in fact, Order, especially as shown in the Mirror Realm involving Mirror Drakath and his friends, the Lords of Order.
Also, as revealed by the Void Larva NPC in the Void, as well as the Great Void Dragon itself, the closest magic related to Chaos magic is Void magic - which is exactly why the Void Dragon entrusted the Lords of Chaos with four different colored Void Spheres needed to unlock the door to its lair.
As revealed on the Chaos Shaper class description, as well as the Supreme Commander armor descritpion in HeroSmash, Chaos is actually neither good nor evil; it is a neutral commanding force that can be harnessed by heroes and villains and neutral characters alike.
