Personally, I always had the nagging sensation that Q's representation of his own powers was somehow exaggerated.
Sure, they are advanced and powerful, but actually spanning the entire universe, from start to finish? I somehow doubt it.
And it would fit with Q's (and Qs') ego. If you were powerful, wouldn't you tell inferior life-forms that you are omnipotent, even if just for shit and giggles?
You know, I've never actually thought of it that way. It does gel with what we know of their personalities. But I'm not so sure it holds up under scrutiny. If you're sufficiently advanced to be able to do the things Q really
can do, what point would their be in lying about it?
Races like Trek's Q or Dr Who's Timelords have always kind of reminded me of Hellenistic gods, in the sense that they are often presented as anything but morally infallible, yet their powers are very much real. Thus, it is the very fact that they have so much power that makes their arrogance so fatal. If it turns out the Q are just faking it, then the moral of their story in Trekdom (that "absolute power corrupts absolutely") ceases to have any relevance and they become just another interesting-as-paint-drying "advanced" race.
And one last thing. From what we now know of the scope of our universe and the basic truths of quantum mechanics, that it's big but not infinite and, given unimaginable amounts of power, that it can be traversed (in time and space), it hardly seems that a race with abilities or even technology as advanced as the Q couldn't be in all places at all times if they wanted to.
And when one looks at all this conceptually, does the Trekverse even really have "old ones" in the sense of the other mentioned series?
My feeling is that it doesn't. I say this because Star Trek generally seems to consider itself a secular series. The idea or trope of the old ones seem to bring with it some ancient wisdom, maybe some dimension of a benevolent being or guiding light. There doesn't seem to be any of this much in Trek. There are old races that have an occassional nod to them, but for me there seems to be little consieration to them as a revered older race with wisdom attached. (Acually I don't think I've explained that very well, hope it makes some sense.)
You've explained it well enough. And you're right, it never actually
feels like there are any "legends" in the Trekverse, in the sense that you get from races like the Ancients in Stargate or the Vorlons (et.al) in Babylon 5. In Trek, outside of one's own history, they seem to be regarded as little more than archaeological curiosities, for the most part. Although, we must take into account that (in the case of Starfleet) we most often see their world from the perspective of "the detached scientist" and that must influence how such beings are portrayed.
