There are ten races of Arcadia, with six of them being of the quadroped, feral shape and the other five, humanoid. The math might sound off there, and that is because chimeras have both a humanoid form and 'beast' form, so they count to both. The ten races are evenly split between mono and omni elementals, with five of each. Below you can find more information of each species/race by clicking on the buttons.

Hybrids are a not particularly common sighting in Arcadia, and this is particularly because inter-species relationships are heavily looked down upon in the mainlands. Though regardless of course, they still occur. The reason for people’s distaste of hybrids, however, is just a fabricated one. Hybrids don’t really cause any defects like a lot of the population of Arcadia say they do. The main one that is thrown around is hybrids being infertile and having a weaker magical ability, but both are untrue. A mule is also a derogatory term for hybrids, used by mostly those in the mainlands.
All that being said, the possibility of offspring, and therefore hybrids between some races is impossible due to major size and anatomical differences. Offspring between feral creatures and humanoid creatures is not possible at all - chimeras are the only ones who have freedom of choice due to having a humanoid form and a beast form. None of this however has anything to do with whom an individual is romantically or sexually interested in, though quadruped x humanoid is rather rare even still. Those kinds of inter-species relationships are looked upon with disgust even more than any of the others.
The most common hybrids seen in Arcadia are lindrakes, which are a hyrbid of a drake and a lindwurm. They're so common compared to other hybrids that they've been officially given this name. They are however often mistaken for pure-bloods, as drakes and lindwurms are sometimes mistaken as being different variants of the same species.
