(I can’t remember all the details, so bare with me while I grocery list it)
She was part of a pegasus tribe in an arctic area (figuring they’re more like snow owls than anything else, birdwise)
I forget why but she was supremely envious of unicorns and their magic
She prayed and prayed for years but to no avail until one day her anguish was responded to by Windigos
They granted her an artifact: this crystal horn you see on her head. it grants her ice powers but at the cost of her loyalty to them…and the fact that it hurts her with brutal frostbite every time she uses it, though she heals rapidly after use
as noted on the page, it hurts her enough that she cries and said tears are instantly frozen. If she isn’t careful, her eyes will ice over completely
Star may wind up with other details for her at some point, but that’s the story thus far. Stay tuned!
