The Archverses are a series of verses which are found practically everywhere across the Omniverse. They make up the majority of verses near the bottom of the containment chain within the Omniverse and can be almost seen as a "building block".
Unofficially, Multiverses can be contained by Megaverses, which then form their own chain, however, they are significantly rarer and only form under specific conditions. Higher level of this type of Archverses can have some Le Jorino Areas in them.
After the Archverses come simply random verses which fill out the rest of infinity located within the Omniverse.
