Dualism

The dualist forces are two ethereal opposite forces.

Overview
The two Dualist Forces are called "Aether" and "Void", called "Anatta" and "Sunyata" in Shibboleth, are mysterious ethereal forces old as time, and severely bend the laws of physics, perhaps the force writing the laws of physics itself. These are complementary forces, and none can exist without the other.

Anatta
Aether, or Anatta is the "Light Force" of the universe. Representing creation and birth. It is seen to be a white misty light. It can be polarized into any form of matter, giving users of abilities based off of anatta to be able to create matter. It seems to be infinite. It is used to create Engram, highly-efficient power stations, Terraforming systems, and faster-than-light travel by the The Empire.

Sunyata
Void, or Sunyata is the "Dark Force" of the universe. Representing destruction and death. It seems to be a purplish-black mist, absorbing all light it hits, but due to it being so wispy does not absorb much light. In large concentrations, it appears completely black. Users of Sunyata-based abilities are able to destroy matter. It is used to create Antiferon, a substance capable of destroying Engram, in turn destroying data, Siva, and all life forms based off of it.

Sunyata and Anatta are not "good" or "evil", each force is just as evil as it is good. For example: Sunyata is able to destroy or kill an evil enemy or substance, and Anatta is able to bring an evil enemy or substance into existance. None can exist without the other. You cannot have creation without destruction or good without evil.
