Vaniian dwarves are rare, distant creatures who live most of their lives underground. This is not out of dislike of the aboveground, as they’re generally rather curious people, but because their long lives spent underground have left them paler than any human skin. They are practically albino in skin coloration and their wide eyes can be blinded easily in daylight. Leaving their deep caves will often lead to dwarves developing absurd sunburns and blindness as their eyes lack natural protection against light that beings aboveground do.
This doesn’t mean they don’t come aboveground though. When they do they’re often wrapped up in coverings and so swaddled none can tell what they are. They also avoid certain regions where the sun shines brightest and the heat is too much.
Side note: their ears are big, rounded things that look almost batlike. They’re very, very cute.
