The Gehenna Tribe was interesting in many ways. In some facets, they were surprisingly advanced, while in others, they lagged behind a larger society.
Their usage of power could be considered a little bit of both.
To preface, the energy in this cosmos was not mana. It was the force Damien had been calling "Demonic Energy," but a name like that was no longer accurate.
The tribespeople called it Barrakh. In the universal language of this cosmos, it was called Malakh.
Either term could be used, but Damien chose the former since he had a good relationship with the tribe.
In any case, both words meant the same thing.
They both were directly synonymous with "energy," just like mana.
Barrakh was a more convoluted and chaotic energy than mana. In easy terms, it was like mana's evil twin.
To use such an energy effectively usually required one to embrace its properties and seek destruction over order.
