Superion was founded by juolfxard in 2024 in the new chunks, further out than the Dulmia World Congress allowed him to, so some of his stuff was relocated to east of the -4000 limit for the years to come. Several months later, however, the DWC had a change of mind when they realized how dense the -3000 limit square was, so they allowed the original settlement as well as the new Henford area and the Mineguy area. Then, I-50 was allowed to continue until the -5000 mark, in which no new Interstates may go in a indefinite timeline, until the Dulmia World Congress meets again.

Superion has two main parts: Old Town and Downtown.

Old Town Center is the oldest area of Superion, started out with a road with a couple stores as well as a park in the central square.

Downtown Superion is the new downtown area of Superion, with taller and fancier buildings than the Old Town Center.
