Janitor Dimension

Named after the infamous Traveller, Strange Odd Shadow, the Janitor dimension (also known as D-NS-4) most closely resembles the Teenyweeny and Bablabla Dimensions, but also shares similarities with Flumberfluff and Belladon.

The Janitor Dimension is featured in Song of the Swans, where Travellers, Intrepid Fusion Eclipse and Kate (I can't find her last name!) from Flumberfluff, Rowana Talmid and the Crateris siblings from Teenyweeny visit its Avant Gardens location.
