Injuria was part of a symbiotic exchange with another of it's siblings, The Murderer, as their power and existence complimented and sustained each other.

Powers: The Primal Demon that is now called Injuria was a trickster of sorts, as it used its constructs, made from the essence it spilled by harming it's body, to protect it's form, and the amount of constructs it could produce was vast, keeping Sunguards at bay with ease. It would also fill The Murderer's form with it, giving it a boost in power, which in turn its sibling would damage Injuria further and grow in strength. Every crack made to it could spill more of its bloodlike essence, but these would reconstruct themselves at a fast rate.

Defeat and Aftermath: Injuria's fall was brought by The Traitor, as the monster drained Injuria of it's blood to keep itself stronger. Without it's assistance, The Murderer fell to the Sunguards. Injuria was able to last longer than its sibling, but soon it was trapped upon it's own form, unable to break itself free of it's regenerative body. The Sunguard would then build a cage with the intent of keeping Injuria's tomb-like body from ever being harmed, and with the purpose to eliminate any that dared approach.
