Which isn't to say that it is impossible. Just remember that, with multi-galactic civilizations, you are dealing with demi-gods.

Or full-on gods, if from out current perspective.

We may even be looking at a race that has learned to somehow transcend physical limitations as well pretty much, making any desires of universal control most likely irrelevant if the physical world is worthless. And since we don't know what's beyond the current universe and the perceivable physical realm it makes what's beyond difficult to ascertain or what would even be the driving aspirations characters operating in that realm would have.

This was the main problem I had when developing my aforementioned alien race. The Xeno I think, or something. Effectively they were a race that learned to transcend mortality and physical bodies and wafted around the galaxy seeking the knowledge that'll take them further. They had no grounding government in the contemporary sense and could communicate across vast distances on an almost psychic channel, basically rendering many of them the same character and the entire collective was a character. And their vast advancement beyond the other races made them pretty much impossible to take, at the same time they didn't give a shit about "worldly" conflicts of the physical races of the galaxy, so wouldn't be involved anyways.

In that sense, trying to grasp the direction they would go in, where the end-goal is, and all of that was beyond my own perception. I couldn't even perceive how they'd get there.

An allegorical comparison to what they were seeking might be the Siddha of Jain mythology. The Siddha being those souls without a body who have attained perfect understand and knowledge of the universe and effectively became all-known Gods. But they don't *do* anything. They've transcended beyond action. That's what I imagine what we'd be seeing in this sort of RP.

From a literary standpoint writing a story from a Siddha would probably be boring. There'd be no progression of anything, no conflict, and no climax. It'd just be 'being'. The only function of a Siddha in a story would be almost like a guide to the lesser races who would be caught up in conflict. Or in the purist Jain interpretation they'd be something the lesser races look to as an example of any of the desirable qualities of the perfect being (absolute pacifism, absolute honesty, absolute non-possession, absolute chastity/celibacy, absolutely not owning more than you need).
