Orc

The first orcs were invented by twisted elven alchemy, meant to serve as war machines against the humans. Their endurance and fortitude were terrifying, second only to the mighty force of will that would soon turn them against their elven commanders.
Escaping into the mountains, free orcs found a higher purpose for their sturdy bones and thick skin: dragon riding. The Algaian Empire very well may have conquered the world if not for the legion-flattening dragon raids carried out by orcish riders.
Now, orcs and dragons live in shared communities throughout the Material Plane. Dragons offer flight, wisdom, and defense, while orcs offer delicious cooked meals, co-pilot spellcasting, and scratches in just the right spots.
Orcs are resilient, thrill-seeking, and don't take kindly to those who would seek to centralize power.
