Inbetween

The Inbetween is a place inbetween dimensions, linking dimensions. Elemental Steve resided there and built upon it. It consisted of many portals going outside the timeline or through dimensions. The middle room has a portal below the glass floor that could possibly, be programmed in some fashion to go to different dimensions. It could also be in the same location of the 'Phantom Dimension' Galaxy Steve was stuck in. As it was also a dimension between dimensions. Not much other than that is known about this place.
