Winter Blossom the unicorn lived in a town plagued by a windigo who caused anomaly cold winters and bad harvests. Winter Blossom’s sister got sick and died during one of those cold winters which made him very depressed.

Meanwhile a powerful unicorn mage came into the town from Canterlot to defeat Frostbite the windigo once and for all. Frostbite was incredibly powerful, but he underestimated his foe and lost the battle. While on the run from the unicorn mage he sensed there was a weak willed pony who was easy to posses somewhere nearby. He possessed that pony hoping the unicorn mage and all the other townsfolk who wanted him dead won’t recognize him like this.

Unfortunately for Frostbite that pony was Winter Blossom (who was so weak because he was still sad about his sister’s death).  Even more unfortunately Frost got stuck in this body forever and lost most of his demonic powers. He has full control of the body and can use unicorn magic. He also has access to both the windigo’s and the pony’s memories which is very confusing to him.
