Junction of Worlds
The term “Kanzaka-verse” is the term that I’m using to refer to the universes described by the real-world author Hajime Kanzaka. The most notable of these stories is the “Slayers” series. A comedy / action / high fantasy series starring a powerful, but selfish sorceress named Lina Inverse, along with her various friends and companions. The world described in the Slayers series is one of four inter-connected dimensions within the same universe. Another one of these worlds is described in another of Kanzaka’s works called “Lost Universe”, which had a slight crossover with Slayers in the series “Slayers: Try”, while the other two have been mentioned only in passing.
Here is a link to a wiki that more fully describes this universe: kanzaka.wikia.com
