Tash also hates world-building for world-building’s sake. So I gave it a go and tried to explain as well.
Every morning at World Builders Co. the builders check in to the Universe Studio. Universe Studio is a testing ground universe on the outskirts of the Multiverse where World Builder Co constructs new worlds and flat packs them to be shipped all over the multiverse. Although at the current rate the company is expanding, the urban metropolis of the Multiverse CBD will soon swallow their studio.
The craftspeople are always first to arrive. Sculpting new landscapes in minute detail is a never ending and thankless task. Geneticists are also fairly early risers as experimenting with new flora and fauna is a slow and unpredictable process. Lastly, after enjoying a good rest in one of their private purpose-built worlds, the imaginators will put in a few hours of work. Talking into the speakers, they will describe new components for the crafters and geneticists to add to their to-do lists.
No-one is sure why the company continues to thrive, given most worlds are bought as spares which will never be seen in all their minute detailed glory. We can only assume it is an old hang-up of our species, left over from the traumatic demise of the Milky Way.
