Arcane Arts is a unicorn working for the Canterlot Royal Research Facility. One day while researching the magic of creating and maintaining portals, she hears a voice call out to her. The mysterious voice causes Arcane Arts to launch an entire research team to investigate how to create a portal into the world the voice described. Weeks of research go into finishing the theories of cross world portal creation, and then it is up to Arcane Arts to tune the portal to where she heard the voice. Arcane Arts is successful, and opens her mind and her world, to the Void.
