High Dwarf (5e Subrace)
From D&D Wiki
High elves are a thing. So are high dwarves. They comes in a more literal sense, however. High dwarves are dwarves born without the size of dwarves. They often average a bit under 7 feet, making them tower over their shorter brethren. As they are still dwarves, they are not necessarily ostracized for their difference. Some hold themselves in higher regard as a tall person, but usually in secret. Due to their physical shape, they are a bit more dexterous than normal dwarves. Oddly enough, they also require very little sleep, being able to go into a trance like elves can. This raises the question of whether they are just bastard dwelf children with a high elf.
