Besides helping space travel, what exactly other powers to the Vacare have? I mean, are they going around shooting fireballs and stuff? Ranting about prophecies and Star Gods?

Star Gods ftw. Whatever it ends up being, I would suggest that we keep a lid on the power level, at least that we see on-screen. Seeing the Emperor in Empire Strikes Back all spooky and sorcerous is awesome. Seeing him shoot lightning out of his fingers...not so much...
