How do you feel about aliens coming to Verra in a future expansion? Not the Ancients, but intelligent life from other planets in different solar systems or even from different galaxies on the material plane.
Premise and Assumptions
Verra exists on the
material plane. There is also the celestial plane, the etheral plane and the void. We know
constellations exist, and we can see the night sky full of stars, so my assumption is that Verra is in a solar system in a galaxy on the material plane.
We also know the Ancients came to Verra in Harbingers, which are comet-like celestial bodies, so I don't think it's reasonable to assume that the sky is a dome shape and that the sun, moon, and stars are embedded into the dome, like ancient cultures once thought on earth. (Well, in the game it kinda is, but you know what I mean!)
This leads to a another reasonable assumption that we could have more solar systems able to hold life in the galaxy, and even more galaxies with billions more solar systems.
Speculation
If other galaxies exist, are we sure that the 10 gods in the current Pantheon are the only ones in the universe? The universe seems like a big place for only 10 gods to rule, especially with three of them having been fired for bad behaviour.
What if other galaxies, or even just other solar systems in the galaxy Verra is in, have their own pantheon and divine races?
With divine portals, any sort of galactic travel is possible, and I think it could be a great way to bring new life to the game down the line, once the more Verran-centric storyline has been explored in the first expansions.
For example, what if the cool, evil gods won the power-struggle in that other place, and the boring, good gods were banished? That opens the game up to entirely new story-lines.
Anyway, it's not something I want to see anytime soon, but it's an idea for the future. Lemme know what you all think

EDIT: Just so we are on the same page, Aliens in this context is like the Eredar and the Orcs and Ogres in WoW, that all came from a different worlds (Argus and Draenor). It's not about little green men in flying saucers with lasers like in Attack from Mars.
