Bound to the Fallen [LitRPG Romance / Harem]

My name is Sol. After the Machine Gods killed the human race, I was transported to a fantasy world. Except it was not a normal world. There was a System, but it was fading and weak. It did not have enough energy to give people Classes and Skills, and another piece of civilization crumbled after each Beast Tide. The only way to gain magic was to hunt for cores, enslave monsters and perform profane rituals. Or do something that everyone thought was impossible. I did it. I forged an unbreakable bond, sacrificing everything to save an angel and a demon from a fate worse than death. Now we are in this together, trying to save a world on the brink of annihilation. The System must be restored, and its secret uncovered. Or else all will be lost to the monsters that roam the land. DISCLAIMER: This story contains wholesome romance that might result in explicit sexual content (extra scenes will be available for Gold Tier patrons.)
