There are certain anatomical differences between Elden and Faun males and females. Such as; the Fauns are slimmer, small and fluffier in size, their eyes are also all colour unlike the Eldens, their horns and fringes are also shorter. They also have secondary horns on their foreheads.
The Eldens have dark pupils and sclera in the eyes, the males also have tendril-like whiskers on their muzzle and on the top base of their genitalia. They also have large hard scales along the top of their tails.
The female Eldens have fans at the ends of their tails which stay open - they also have fluffier ears and their fringe is separated into two either side of their heads.
Their differences don’t have any ability attributes, anatomical only.
