Skybreaker

Your name is Zulira Aetheria Truesky. Over a millennia ago, your ancestor, a powerful celestial deity/mage. Lonely and bored of his duties and being stuck in his celestial palace with his followers/mages. He gazed through the dimensions out of boredom, on Earth he spotted a woman he fell head over heels in love with. He watched her day to day from his palace, craving her evermore and forbidden to contact the non magic dimension. His jealousy grew as he saw competitors for his beloved’s heart, which led to him forever abandoning his post and giving up his extended life and status to become mortal. It took his followers/mages over a millenia to learn what happened and where he went. Once understanding, they began tracing down his lineage of all his sons since his kind's lineage tends be all males. Their world has been left without a Skybreaker for so long their world is falling into chaos and disarray. You must restore it, but the beings in that world have a hard time believing that you’re the Skybreaker since you’re a girl and have no idea how to use magic. Some people also hate you, blaming you for your ancestor's action of running away from duties to a non magic world to enjoy his life as they suffered. You always thought that you were an ordinary girl until one night you were summoned to a strange place with three hooded robed men. They lifted them of your shorts to see your weird birthmark on your thigh. As they were distracted, you jumped through a portal that looked like it led to her room. Before you knew it, you were back in your now bed-less bedroom.
