headcanon; on baba yaga's riders and their immortal mounts
according to the fairytales, baba yaga had three riders who would ride through her forest and bringing with them the Day, the Sun and the Night. in some they would even be called her very own children.
however, the fairytales are partially false -- the sun and moon, elois and malvolio, have always had a connection with the baba yaga in some form or another, though most prominently the witch was connected to the fifth (luce and helios) and sixth (sunny and puck) generations of these spirits and, from her own blood, she provided them with two immortal mounts as gifts to her new 'grandchildren': one, a pure white horse with a mane of fire, and the other, a horse as black as night with stars adorning its mane and galaxies in its eyes.
another name granted to the sun and moon due their connection to the baba yaga was established, is zorya -- or auroras -- and they are described as immortal gatekeepers who watch over the immortal doomsday hound known as simargl -- an epithet of fenrir. this story is derived from the binding of fenrir, inspired by the real event of the dread wolf making an attempt on the lives of an earlier generation of sun and moon spirits, where baba yaga, along with the norse gods, crafted an enchanted ribbon and used it to bind fenrir into human form to protect elois and malvolio.
