These three races, while each individual in their own rite, are catagorized together for one main reason: their Creators. The Ana'aea'aek, quite possibly the strongest daughter gods in Aryneth, claimed their own races, while no other offspring gods could. The three "fates" of Aryneth, Se'elaime, Styrix, and Sair, decided they wanted to have their own creatures underneath them, to aid them in making what they wanted to happen, happen. Se'elaime's creatures were inspired by the goddess Aerelle, being fair and beautiful with wings of glistening white feathers. Meanwhile, Styrix and Sair made theirs in their own image, ghastly creatures of demonic appearance, differenciated only by the colour of their hard, tough skin, just as that was the only way to differenciate Styrix from Sair at the time. Styrix take on a dark red colour, that of dried blood, perhaps, and Sair have a dark green colour, as Sair was often the jealous one of the three. Of course, when they presented their creatures of Hadesari, he remarked often over the Elaime, which immediately the Ana'aea'aek took notice of. Always wanting to win over Hadesari's attention, they transformed themselves into a more appealing creature, beautiful and humanlike, but with the same wings as their respective races. This change effected the Elaime not in the slightest, but the Styrix and the Sair held no qualms about it, understanding that, while their Creators no longer held the same image, they still found them beautiful even if Hadesari didn't.
To recap, the Elaime are basically angels in appearance. The others are deamons, the Styrix with a crimson colour and the Sair with a dark green.
The Elaime, the Styrix, and the Sair are very rare around Aryneth, spending most of their time in the Nexus until ordered to carry out some request from the Ana'aea'aek. However, a few have gone on their ways to pursue more Arynethian lifestyles, especially the Elaime, torn between two sweet and generous ideals (Wintaer and Se'elaime). They tend to live particularly high in the mountains, thinking it makes them closer to Aerella while living their mortal lives, while the other two tend to dwell underneath, knowing how ill-recieved their appearances are by the general population of Aryneth.
