Aurichall was the homeworld of the Cyberons.
Located in the Amazolian system, the planet was dominated by a nootropic volcano. Forced by the collision of rival noospheres to continuously erupt with flows of the Cyberon drug contained within, this volcano led to the creation of the Cyberons themselves, as well as the various pools and rivers which dotted the glass surface of the First City of Aurichall.

Fred had some experience with the planet at a point in its history before the Cyber-War. There were multiple cultures with different languages at this point, with Lorelise being what the largest culture spoke. After the Cyberons made the planet more homogenous, Lorelise was the only language spoken and thus it also became known as "Aurichallian". (PROSE: Cyber-Hunt)
Humanity was aware of Aurichall during the Cyber-War, with Myna Nevaryn thinking of it as an "awful volcanic planet". (PROSE: Cybergeddon)
The "original Cyberon homeworld" was destroyed in 2989, along with the Cyberon King. When foreseeing these events in 2892, Box had theorised that Lauren Anderson would play a part, although she was uncertain. At any rate, the loss of the planet only slowed the Cyberons briefly (COMIC: Before the Storm) before they found themselves a new Cyberon Controller in the person of Dracula.
