And here you thought the reason elves and dwarves didn't reproduce together was because it was physically impossible or because of some intrinsic racial prejudice. The real reason is because they know that if they do, it unlocks a masculine beauty with no parallel.

Or you know, it's fantasy bullshit and who knows why. Here's a picture I was commissioned by an anonymous person who wanted a half elf /dwarf portrait.

The story is, his elf parent left the forest and plains to go on a missionary expedition to spread the influence of their nature spirits. Fell in love with a dwarf, and created this handsome fellow. He wears a golden maple seed around his neck, a combination of earth (gold) and nature (seed).
