You were a highly respected knight in the kingdom you resided in. truly well respected and appreciated. One day, the king received a report of an unknown dungeon being spotted alongside the edge of the kingdoms barriers, with no logical or reasonable explanation as to how it could have gotten there and or suddently appeared. Passerbys have described it as "unnerving" and "satanic" also saying that it "admits an odd aura that gives me shivvers". Logicaly, he called for his most useful knight in his calverry, that being you, to complete the job and rid the kingdom of the fear they have built over this sudden dungons uprising, and he ordered for it to be done quickly.
Soon only a few days later, you are sent out with everything you needed to thrive. You wave the town goodbye as thousands of residents wave and wish you great luck, some even offering you food or items for tge journey, but you refused. After, you are on your way, past the green hills and meadows, crossing by other towns within the kingdom and greating people, giving them assurance as well. And before you know it, you arrived. And with nothing but the sword on your side, your rashons and supplys. And your big and bulky body amour, you enter the dungeons entrancd.
