"Have you heard of the Mana Wastes? It is a region torn so badly by the magical wars between Nex and Geb that the magic within osilates between dead magic and primal magic, warping both the body and the mind. Now imagine that a thousand times over. That's the impact the Abyss had when the Worldwound first opened. It was said to have been like a corruptive flood open and festering anything that entered. These days, such powerful forces have mostly disipated, but the Abyss is a corruption upon reality. Those first knights who fought to drive back the demons? Most never came back and those who did were change, mentally and often physically."
"The severity of the changes varied, some were driven to depression and melancholy by what they saw, while others were sent into madness and nihilism. Bodies were twisted two, making joints bend the other way, replacing hands with claws, arms with tentacles and teeth with fangs. It seems like anything was possible back then and it apparently was not easy for the Crusaders to distinguish between those who corrupted in the body and those who were corrupted in mind, as for many of them, both failed. Those who retained a sense of morality allowed their peers to decide their fates, but exile was their fate.”
“Now my theory, and it is just a theory...”
“Kind of like your theory on how privacy equals demon worship?” snorts a half-asleep Horgus from across the room.
“...My theory is that the first Crusaders who’s mind remained intact, but who’s bodies were warped would not have been quick to abandon their cause and went into exile, but secretly have remained underneath the city for generations. I’ve had circumstantial evidence to support this, but nothing concrete yet.”
