There had always been a great risk for those who stepped onto the battlefield to fight demons: The Demonic corruption.
It was one of the most feared dangers in all of Arventia, a curse that did not wound the body, but twisted the mind.
Even the calmest and kindest soul could be consumed by it, transformed into a bloodthirsty monster that could no longer recognize friends or family.
The cause of that was quite straightforward.
Where demons walked, the air itself became tainted. A thick miasma would seep into the land, clinging like smoke, and demon blood carried an even worse corruption, as it was unnatural, hostile to all living things. Like a toxin, the longer one remained exposed, the greater the danger became.
Demonic corruption might not happen instantly though. It was not like flipping a switch. Sure, if given a strong dose of that toxicity, of course a person would instantly be corrupted, but it could also happen slowly, silently.
