I suddenly felt like making an OC, so here is Seraphine.

Despite her Unicorn father and her Bat pony mother, Seraphine sprouted neither horn nor wings. Only resembling her parents with her sharp features and unusual affinity for sorcery, she was treated as an alien. Her family is part of a secluded clan residing deep within an eastern forest. Like in many ancient forests, nature moved on its own accord. Seclusion and harsh environments gradually molded her clan into what they are today, deeply pious beings with rich customs and harsh spiritual guidelines for all in the community.

Rumours began to spread in the clan that a strange little alien foal was able to speak to the forest itself. Seraphine eventually ran away from her clan, sensing that she would be witch hunted if she didn’t escape beforehand.
She packed what she could carry and headed West, out of the great dark forest. She eventually entered a hospitable realm governed by magical guardians so powerful, they could control the sun and moon.
