The Door

The Door refers to the primordial black hole found under the surface of the planet Iso that acted as a barrier between the Shodai’s universe and the dimension of the Exoswarm. Much about The Door remains unknown, such as where it came from and how it was used to keep the Exoswarm from escaping. It was the Shodai’s experimentation on the Asterstones that caused them to unintentionally open The Door and release the Exoswarm on their universe. It was later discovered that Iso was a great source of Attenuation, the term Shodai used for the thinning of spacetime that creates connections to other dimensions. Although sources of Attenuation can be found throughout the universe, only the power of the Asterstones can open these rifts and connect dimensions.
