Random DnD creatures. And a drow race mod with a halfdone language file.
GDF elves and their endless subraces. Drow, dark elves, night elves, shadow elves, orcs (tolkian), sun elves, sky elves, moon elves, snow elves, prairie elf, tundra elves, ice elves, Elvis, wood elves, forest elves, Keebler elves, amazon elves, jungle elves, Dryads, psychic elves, magic elves, oracle elves, seer elves, musical elves, wandering elves, mortal elves, lost elves, (almost) forgotten elves, wild elves, Santa's lil'helpers, Harry Potter's lil'helper, desert elves, sand elves, high elves, eladerin, steam punk elves, cyber-elves, nerdy elves, futuristic elves, space elves, eldar, darl eldar, Vulcans, wannabe elves, zombie elves, tree elves, winged elves (which are not to be confused with FLYING elves), genie elves, demon elves, vampire elves, pointy-eared hippies, evil elves, edible elves, cereal elves, and Hylians. Then there's a giant for each, and a half-dragon of every colour for each. Then a half-dragon, half-demon, half-giant, and/or half-elf version of each.
And there's no such thing as a fat elf. They're all supermodel thin and ultra healthy.
There's a mod idea. Replacing everything with elves. Call it the World of Elves.

One idea I had was adding [TAMABLE_EXOTIC] to fire imps, and giving them gender and baby making. Breed them, then chain them up and use them as guard dogs.
