Re: Old races, new tricks.
I once flipped dwarves and elves around to get Wood Dwarves and Mountain Elves.
Wood Dwarves were woodsmen, a less-cartoony version of Snow White's gang. They were forest caretakers, cutting down this sick tree, planting a sapling there, keeping the forest wildlife in balance. They couldn't speak with animals per se, but such was their familiarity with the woods that they could attain an almost supernatural clairsentience with what was happening within a mile or so. Typically they operated in small groups of around, uh, seven, but many lived alone, and hidden Dwarven villages were scattered throughout the woods as well. Expert hunters, trappers, and woodworkers, the Dwarves were inherently somewhat magical; some could go on to join the ranks of the Druids.
By comparison, Mountain Elves were more feral, living brief lives of tribal warfare on the high peaks and in the deepest crevices. Not miners, they traverse sheer rock faces using their mountain goat-like agility, and navigate the narrowest crevices underground by dint of their slender limbs and extreme flexibility. These Elves are masters of concealment, able to fit into impossibly small spaces under boulders, or appear to vanish into a rock face simply by remaining immobile. Immune to the cold, they routinely travel the highest reaches of the mountains, but often visit the rocky foothills as well, all in their quest for valuable ores which they work not through smithing, but through outright magic. A Mountain Elf cannot be bothered to carry something as bulky as a bow and quiver, but Elven knives are the keenest in the land. Sadly, this knowledge of metalworking is one of the few talents remaining to the Elves, who are the last survivors of a once-mighty empire that spanned the continent.
