The Inkless Codex : Sin Eater

In a world were evil runs rampant, even a glimpse of certain entities can drive a person to madness. The truth about these horrors remains hidden from the public, buried beneath layers of lies and secrecy. Standing between humanity and the darkness are the Inkbounds. By harnessing the power of abstract concepts known as Factors, the Inkbounds gain the strength to fight the entities lurking in the shadows. But this power comes at a terrible price. With every step towards greater strength, they risk losing their sanity, their lives, and sometimes even their very identities. In a world where knowledge can shatter the mind and power demands everything in return, a young boy struggles to survive against forces beyond his understanding. His journey will take him into the depths of a world consumed by madness, beyond the curtain of lies, where the line between monster and human grows thinner with every passing day. Because in a world like this, staying sane might be the surest way to die. And sometimes, the only way to survive is to go mad yourself.
