This work is a participant in the Royal Road Writathon challenge. (April 2024) Eric Smith is a high school student on Earth. He wishes he could live another life as Stormrider the Lightning Wizard, a character he draws while bored in math class. His wish appears to be granted as he is unexpectedly summoned to enroll as the newest student in the Royal Academy of Astraeus: a school in a different world focused on magic, combat, and protecting the kingdom from the Enthralled army. But things don't go as planned. Not only does Eric fail to acquire any sort of Lightning Wizard class during his class selection trial, he ends up with a class that causes him to develop two identities which both exist simultaneously in his mind: Twinborn. He wakes up in a new world as two fledgling magic users under the same control: a sixteen year old boy named Aeric and his fraternal twin sister named Elsie. Being warned not to reveal the true nature of the Twinborn class, while also struggling to come to terms with having two identities existing within one mind, can Aeric and Elsie successfully integrate into the Royal Academy of Astraeus and become the heroes they so eagerly wish to become? What to expect: a summoned-to-a-new-world fantasy magic progression story with more focus on characters than on numbers going up. Once it gets going you can expect more slice of life chapters than combat chapters, though combat will be present throughout the story. Hope you enjoy! :) What to REALLY expect: this is my first story I've ever posted anywhere for other people to read, and it's also my first story that has ever gone on this long. So basically expect it to sound like a story written by someone who has no clue how to write a story. Still hopefully an enjoyable read though!
