These are the two closed species I am active in
Fables and
Wild Mountain Equids. There are plenty more but those are 2 I am in.
WMEs cuz I like horses lol
Fables has some unique features especially. Once a month you can either
Color in a Make Your Own (MYO), commission an artist to color in the MYO lines, or claim an
artist search entry (if artist allows). You make your adopt official with writing or art c: so it only costs you your time to get into the species. I have been in species where I try and try to adopt for months. Not so in Fables.
They also have a
seasonal nursery (right now it is summer) that gives non-owners an opportunity to get a semi-custom! For free ^^ once you own a fable you can breed your fable in the nursery even if you own just one! It's called single parent breeding (also unique!)
I recommend joining the fable discord if you are interested c: everyone is nice and will help you get started. Okay bye!
