Eternal

By no exaggeration, some of the paths in this story are a novel by themselves. This is a piece of grim-dark fantasy genius. Eternal isn't a story about a King that has a strong democratic personality that lets any peasant speak to him as they like. This is the story of an Empire's last-ditch effort to stay strong by building a race of super soldiers. You can be one of those supersoldiers

There's very little bright in this world. If you make the wrong decision, you're grave meat. If you make any other decisions entire peoples will die off, kingdoms will fall at your feet, Monarchs will die at your hands. People will try to use you to their advantage.

Be warned though. Terrible things will happen to you along the way. Well-adjusted individuals don't conquer the known world in a lifetime.
