The beginnings of the Dwarven King

I actually ended up living another life in a fantasy world?! Shall I be the hero? The demon king? An adventurer seeking glory and wealth? No, I shall become the first of a staple fantasy race! Time to be reborn as the Dwarf King in a world that lacks the staple fantasy races, while I am at it why not be the first to own and operate a dungeon? This shall make for a perfect way to found and grow my Kingdom!
