The "inter-universal cafe" for a thousand Earth instances is the setting for a chapter in Strung Out in Demiurge, one of the Alphazett Chronicles stories in development. The building concept was an architecture competition entry from decades ago that I reinvented a few years back as a feature location to fit somewhere in an Alphazett narrative.

The character of Thelonius (Ted) Dent, featured on the cover, is a grizzled Agent of Retrieval, member of the Agency, the central glue of the Alphazett Multiverse  that literally keeps the whole shebang up and running.

Originally, these two concepts, the building and the character were entirely unrelated. Realizing the building was the original goal, but by tying it into the larger story, I suddenly have the story to shape the building narrative.
