It is no secret that airplanes and land transportation are the cheapest methods of moving goods and people throughout the Celestial Plane. Compared to the Divine Realms the twins had visited before, the entire structure of society and transportation simply functioned differently here.
One could naturally try to rely on Spatial Rings for transportation purposes, but rings with truly useful internal spaces were absurdly expensive. Only major powers or extremely wealthy experts could afford to use them on a large scale. Because of that, most cargo and personnel transport still relied heavily on airplanes, caravans, trains, and countless other conventional methods.
Nonetheless, that did not mean the Celestial Plane lacked Teleport Arrays.
