Void Sphere

Void Spheres are containment constructs, used to create a bounded area for a battle. Because fighting in the actual universe causes catastrophic damage, they are often used in battles among gods. Once deployed, the boundary cannot be crossed and will remain in place until the energy of the Sphere runs out. It both stops combatants fleeing the battle field and keeps anyone else from intervening. Void Spheres are extremely difficult to obtain, as creating one usually requires the corpse of a Void Dweller. In the days before Jake's confrontation with Ell'Hakan, Arnold was able to make a greatly diminished version adequate for C-grades.
