Last reference was done in 2011. I think Arthaios was created in 2006, but details are fuzzy. Those are the oldest drawings I still have. Feral is again a retrace.

Details;
Arthaios is a true hermaphrodite and uses Shi/Hir pronouns.
Due to hir creature type shi does not produce sperm or ovum.
Arthaios' true being is most closely like a Biblical angel. Hir true form is a swirling ball of light in hir base colors.
Shi is one of four, for lack of a better term, siblings of light and dark.
Hir name is based on arkhaios, ancient.
Shi can shift into any creature, but hir coloration will be the same along with certain details.
Hir favorite forms are a feral eight legged song horn and an anthro horse.
Hir forms, while they can be large, are always proportionate.

My Arthy fursuit, while inspired by Arthaios, is a different character.
