Hriston
Dungeon Master of Middle-earth (He/him)
Because the Chainmail Fantasy Supplement was written in part to suggest ways to use figures of different scales all on the same battlefield. It is also partially an adaptation of a LotR-inspired war game, so it had to have hobbits. Gnomes are included for the same reason there are kobolds and faeries. Each of dwarves, goblins, and elves were given an alternative variant of diminutive cousins.
