The Universe
There are locations across the universe where the boundaries holding the Aspects apart grow thin. In these locations, Novas can draw on energies from the five Aspects, allowing them to summon monsters and use epic powers.
In many of these locations, arenas sprung up where two Novas can test their skills against each other, battling with summoned units and epic powers until the last Nova standing wins.
Each Nova selects their own deck of units and powers, and brings it into the arena with the goal of knocking out their opponent. Some Novas focus on one aspect, while others attempt to draw on two or more aspects at once.
