Horse Gallery address?

[Stegosaur's Lover]

So there was this excellent horse gallery that I think was hosted on a russian site, however I can't quite recall the address. It was like a booru style place for pictures and videos. I sadly cannot remember the name of it. Any help?

Yes that's the one. Sorry, I only knew the address by the "callista" part of the address.
