Underground Dwarf Village

Hey! I see there have been suggestions about this already but I would like to send my thoughts in anyway. So underground villages, dwarfs is known for mining and their strong equipment and I was thinking it would be a great idea to give underground more friendly creatures and why not characters known for loving the caves! My addition to the thoughts is that maybe we can have a master craftsman that needs supplies from end to craft stuff as strong or stronger but in another way then Netherite? I was thinking of maybe you balance it to do 2 different things and give the players the option to choose what to upgrade, netherite or Dwarven end steel, so the player have more versatility and can choose and not follow the same path to the same end every time ^^ obviously make dwarfs tradable and give them unique things that can only be found there, maybe a special mob just for them.
