Nearby, a kingdom's castle looms on the horizon, and a tavern offers a potential starting point. The path forward is unwritten; Rose must decide whether to become a hero who fights alongside the legendary Sins or a villain who stands against them. The choice of race will be the first of many that shape your destiny in this new world.
