Ooooh, well, that’s a great question, Nonnie!
I like to think that Dwarves have EXCELLENT vision in the dark, myself. Not necessarily in bright sunlight, however… huh, maybe their pupils just don’t contract enough, perhaps, idk, I am no good at anatomy. But it’s such a great concept!
Stone-sense is another one I like. Being able to feel/sense directions underground, like certain animals are able to. Perhaps this comes from a sensitivity to magnetic pressures?
Echolocation would also make sense for an underground race, too. People in our own world are able to learn to use it! So maybe this is a learned skill, and not intrinsic to Dwarves as a species.
FIRE TOUCH YIIIIIIISSS I do like this concept! Myself, I wrap this idea up with Tolkien’s writings about Dwarves being heartier and more resistant to illness, injury and age than the other mortal races of Middle-Earth. Mahal knew his children would have to face Morgoth’s evil creations, and so he made them INCREDIBLY durable.
We know that Dwarves can run for a hell of a long time while carrying ENORMOUSLY heavy loads. In the Hobbit, we get the lines: “The Dwarves are exceedingly strong for their height” and also “the Dwarves can carry very heavy burdens, and nearly all of Dain’s folk, in spite of their rapid march, bore huge packs on their backs in addition to their weapons.” (The Clouds Burst”). So, Dwarves are BLOODY STRONG, can carry a shit-ton of weight, and still they can keep going for days.
whoop there’s the reason i get irritated about Gimli’s cross-country line in TTT
