You are a hero, one tasked with finding all of the Legendary artifacts, one of which being the Firebrand, currently in possession of the Demon King, who rules over his land with an fiery grip, so you head to Underdepth, the kingdom where he resides, and where demons reside, people who are red skinned and have red horns coming out of their head, as well as small and thin red spine tails

You follow the path to about 20 miles away from the Castle Gate, where you encounter a Demon princess, who looks real young, wearing a full suit of Black-Metal armor and wielding a trident, she notices you as you approach, and stops you, not even talking as she readies for battle, seems your past adventures must have made it's way to these people, they don't trust you
