The Portal Nebula is a supernova remnant that appeared around 196000 CE. For many lightyears around, local planets enjoyed the light show. The former star that created the nebula, called the Portal Star, was anomalous in its own right for it having strange gravitational effects that affected any ship that passed within its vicinity. It was utilized to create simple dimensional rifts and portals, hence the name.
