@Mr_NutterButter It's the lore of my three boy OCs! My main OC Velnohs (the one in my pfp) was born into a clan of swordmen, The Nero, who house a vital relic used for the balance and vitality of three connected realms. Those being the Light, Mortal, and Demon realms.
The swordmen can't use the dark magic needed to stabilize the relic and only a guardian born from one of the royal families is able to wield it, that being Velnohs. He is to be sacrificed to the relic when he gets older. But there is outside interference and he gets kidnapped from the clan. Since the guardian has gone missing, the three realms start to fall apart as consequence from the unstable relic and other various sources of interference with the ritual.
I started it last year and kept writing and writing. It's already 350+ pages and I realized it's pretty much a damn mini book at this point. I'm nowhere close to ending it so I expect another 300+ pages.
