I found the exact-ish information of RHG

RHG = Random Horse Generator, I was using it as I wanted to be a little more unique until I came across a description that sounds exactly-ish of Solstice! I wasn't paying attention to the rest but a seal brown mare? If I know Solstice then she'd be in that exact description!

See: Your horse is a 14.0hh pangare seal brown mare. She is a sweet 6 year old with a stripe and snip marking on her face, and her four leg markings consist of a sock on her right front leg, a pastern on her left front leg, a sock on her right hind leg, and a sock on her left hind leg. She would be best suited for show jumping. She may be a Nokota Horse, a Morgan, or an Australian Draught Horse cross.

Okay well not at least Trakhner, but close as it describes the first part! How crazy is that to find a friend's horse in something?! Well maybe not, but I think it's cool at least- at least something to let me draw.. But not close to a friend's/rper's horse.. Haha..
