| Void energy |
Void energy is powerful and evil energy from the Core which corrupts whatever it touches and explodes onto the surface Moonlands through Shadow Geysers. Corruption by void energy is the source of corrupted Shadow Magi and Shadow Creatures.
Void energy tainted Agram due to his anger because his brother, Padram, had fallen in love with Une, whom Agram loved. When Agram and his allied Magi were imprisoned within the Core for allying with the Invaders, void energy radiated from the prison's Black Animite walls eventually corrupted the prisoners and the Core, itself.
Agram later harnessed this void energy and created the Shadow Geysers in an attempt to release himself from the Core. Despite not being freed, the geysers of void energy nonetheless signaled the Invaders to return, this time to the Moonlands.
Void energy could be released through an Allegiance Relic, as when Amara was purified by Strag. However, void energy also was channeled through an Allegiance Relic in order to corrupt Orwin into a Shadow Magi.
