I love dwarves!!
Specifically, Dwergari, my original species, I really enjoy working on and I have a HUGE world built for them.
I used to have an MSPFA featuring dwarves, but it's since gone inactive, although I intend to bring another one into existence solely focusing on them and their world.
They hail from planet Ivaldi, a world split up into 4 continents with different kinds of climates, and each continent containing some kind of magical artifact which the dwarves use in their everyday technology. Although their world is quite fantasy-adjacent, they themselves don't really use magic directly and are more like artificers; creating objects that are imbued with ethereal elements that they can use. You'd see a dwarf taking a flamethrower into battle before you ever see one casting a spell lol.
I definitely plan to update their entry in the Fanspecies wiki but for now, it's fun to work on them in my own time and I hope they can turn out to be one of my most developed fictional species I've ever worked on.
Excited to see what other species people here post about too!!
