Underground Villagers - Dwellagers

An underground village populated by villagers similar to dwarves but called dwellagers to fit the theme of minecraft. They could trade amethyst, copper and new 1.18 items. Also could build structures out of copper and not be able to trade above sea level to keep trading farms in their natural environment. They could possibly use a primitive form of electricity with a structure containing a lightning rod on the surface similar to an azalea tree marking where a dwellage is. Electricity is obviously something that wouldn't be added to minecraft for a very long time but maybe if it was done through 'overcharged redstone', glowstone and redstone crafted together to make charged redstone that can travel a signal further and then connected to a lightning rod to created overcharged redstone which can carry 'electricity' which certain new blocks can utilise. If this gets enough up votes I'll make the overcharged redstone a different feedback.
