@VecHow'd it work? Like a webway?
It's a very early alpha idea. It sort of came to me when I was thinking of ways for the Avatar to quickly travel from planet to planet.
Think a sort of different dimension where the divine essence is so thick that it enables for multiple portals to different galaxies to form. There would be a single, massive planet orbiting an equally massive star, tentative as for the star being Ull'Yang or not. This planet would be a sort of crossroad between all the galaxies where all races from every corner of the universe could pass through in order to travel to a different galaxy. There would be a huge city there and in it, a big, temple-like building where the portals would be located. Every galaxy that possesses living sentient creatures would have a dedicated portal in that temple.
