The multiverse (in Coraabish minthokarr) is an all-encompassing term for the transplanetary territory that comprises all civilized and uninhabited worlds across Coraabia.
Multiverse is interwoven in many directions by a galactic string that makes distances between individual places in the space relative. It was thanks to this string that the term multiverse became popular despite its usual usage reffering to existence of parallel universes. In earlier days, it was hypothesized that strings led to alternative realities, which was later proven wrong - all worlds of Coraabia are anchored in the same timespace continuum.
While some still maintained the position that certain strings in Coraabia led to alternative realities or dimensions, no such string was ever oficially discovered or scientifically described.
