Of the world-bound races (that aren't Men, basically), which one is your favourite?
I love me some fucking dwarves. They spend their entire time making shit and mining for the sake of making shit and mining, love Aule, and don't take shit from anyone.
You make a glorious necklace, lend it to some Elvish king as a sign of respect and friendship, he sticks a Silmaril in it, and then claims it for himself and his children forever. What do you do? You kill him, take the necklace, and go home.
You're in your oldest mountainhome, which is essentially just a hollowed-out mountain. You dig deep enough to encounter horrible nameless things that make a Maia blush, so naturally you make a staircase from the very foundations of the Earth to the rooftop of one of the tallest mountains on the planet. For shits and giggles. Then some fucking balrog cunt comes over and smashes your shit in, and your ruins are still more glorious than pretty much anything east of Valinor.
Dragon take over a mountainhome? Bring a wizard along to help you retake it. Sauron offering you a bunch of magic rings that magically multiply your wealth? Spit in his eye once you realize it's slavery. Sauron come over with a thousand armies a mere 60 years after you barely retook your mountainhome? Beat them off and remain one of the fewrich realms in the land. Then go recolonize your ancient mountainhomes, colonize a new cave system in the white mountains, and go make some indestructible doors for a human king as a sign of eternal friendship.
Dwarves. Stout of height and heart.
