Other Worlds (Other Worlds)

Selenophos is but one solar system in the Milky Way, and Ignis and Maquette are but two dimensions. There are many more places that Dextroluma, Dexettes, Nunuluma, Lockettes, and Kipitins can be found, and species who have relations to them.

These vary from planets, magical dimensions and realms, space stations and ships of all sorts...  Every place is different.  The greatest commonality is that wherever Dextroluma go, their homeworld will do their best to keep them connected to a supply of mushrooms.

That said, some destinations are more common than others - species that Aerius currently has formal relations with or has formerly had relations with tend to have higher populations of Dextroluma than ones they are less connected to.  Still, it's a big galaxy, and they live long lives.

Lockette and Kipitin populations tend to not permanently reside in other worlds, but it is not unheard of, and is more common to Lockettes than to Kipitins.
