#nerdoff Haha in all seriousness you do bring up excellent points, however I still feel inclined to put my money on the Star Wars universe if I had too Unfortunately the majority of star wars' extra dimensional beings aren't fully "explained" although we do catch glimpses of their powers and machinations through out the EU. Unfortunately due to f[u]u[/u]cking Disney, we most likely won't ever get a huge background on say the Celestials; who were known to have destroyed hyperspace routes throughout the edge of the galaxy for unknown reasons (although it is speculated that they did so to halt the advance of Mgnnal-Mgnall), scare extremely advanced races (such as the Sharu and Columni) to check their expansion and even revert to a primitive form of living to seek refuge from the notice of the Celestials on the case of the former. (It is also claimed that the Columni, while extremely advanced at one point, actually retreated from the stars after encountering the Celestials). They are also credited with creating massive objects such as centerpoint and sinkhole station to check the creature Abeloth, and created entire systems and clusters such as the Corellian and Vultar systems, the Hapes cluster, the Kathol Rift, and possible the Maw black hole cluster. They're also credited with potentially seeding the inner core with life other than just humanity. The Ones are also incredibly powerful force users said to be related to the Celestials in some way, although the extent of that relation is never fully explored. The Celestials are pretty formidable and mysterious, but again F[u]u[/u]ck Disney, they ruined so much of the EU:-/ [spoiler]also I hadn't heard much about the precursors or their abilities before this thread, do you have a source from the Halo EU that fleshes out their race? It sounds extremely interesting[/spoiler] I also find it interesting how both these advanced races (Precursor and Celestial) were both usurped in some way by those they created/nurtured to an advanced state (forerunners and Rakata) and disappeared from the galaxy at large.
