I liked the last issue a lot. So I guess the El-Aurians are the Trek version of Time Lords maybe?
Not really. They are very long-lived (Guinan at least five hundred years old in the late-24th-century), their homeworld was destroyed by the Borg, but by and large they're normal humanoids.
Guinan is somewhat unique, as we learn later in Star Trek Generations
because of her encounter with the Nexus in 2293. There's a part of her that's always outside of time. That's how she was able to sense that the timeline was wrong in "Yesterday's Enterprise
," for instance. The other El-Aurian we saw that had the same encounter with the Nexus, Tolian Soran, was driven pretty much mad by it.
