Rough Draft of Lore:
Drasper live up in the mountains where they survive off metals, rocks and minerals. They product crystals on their body as a byproduct of their diet. All of them have the ability to float/fly without wings, using their long tails to steer themselves in the air. They all have horns, hair, and manes regardless of gender. In fact there is no way to distinguish what gender a Drasper is by sight and biologically gender seems to play no part in their ability to survive or reproduce. They possess a lot of traits that make the species very diverse but still distinctly one species.
Drasper are a very intelligent and sentient species. They love to interact with other species and communicate through telepathy. They have their own language but often enjoy learning a new language to communicate better with other species. A young Drasper will often parrot random words back at someone they are trying to befriend.
Lagomoons can frequently be found at Drasper side as they survive off a "Goop" Drasper frequently finds when digging for metals, rocks, and minerals. They cannot take flight with their wings but use them to slow their fall when they leap off too high in the air. They come in two varieties Feral and Wild, Feral were once tamed by Drasper but have since been released back into the wild, they are much easier to tame and once tamed become a Domesticated Lagomoon. Wild are from populations of Lagomoon that never took to living with Drasper which makes them much harder to tame and once tamed they become Exotic Lagomoon.
