Why Is There No Half Dwarf?

Biological incompatibility is the first and foremost reason that such half-races cannot exist. Simply put, dwarves, gnomes, and others just aren't compatible with other races, even humans.

Are half-dwarves possible?

Half-dwarves were usually the result of a dwarf mating with a human, gnome, elf, or halfling. The offspring of a dwarf and an elf was known as a "dwelf" (which was pluralized to "dwelves"). The fertility and offspring of half-dwarves was similar to that of half-elves.

Can humans mate with dwarves?

Dwarves were one of the first races and humans have held the Armlet of Strength. Therefore half-dwarves are capable of interbreeding with humans and continuing to produce children. Breeding with dwarves is usually unsuccessful and results in sterile half-dwarves .
