So I'm making a faction called the Draetor Empire, who are, well this.

[i]"The Draetor are an ancient race of biologically immortal humanoid aliens, rumored to be as old or even older than the Ashtar themselves, who achieved a form of energy based ascension in ages past thanks to their experiments into the nature of energy in the observable universe and several close joint research projects with the Ashtar and their psionic technology. Also, despite being structured and operated like a traditional empire, the Draetor value scientific and cultural advancement over conquest and imperialism, meaning that they are a rather peaceful race and, as such, did not participate in the Great War.

It should be noted however, that even though they are not a warlike people by nature, the Draetor still see the benefits of having a reasonably strong military presence in their sector of the galaxy and will not hesitate to go to war if attacked."[/i]

Anyway, I was thinking that instead of living on planets, they instead live on one massive hyper-dreadnought around the same size as Jupiter (possibly), which is powered by the energy siphoned from stars. And let me make this clear, the drained stellar energy would be for travel purposes only. Nothing more, nothing less. Other than that, I was thinking they move from star system to star system every hundred years or so and exchange knowledge with other races.

So, does that sound acceptable? Or is it too OP? Also, I might just limit their involvement with the Ashtar to brief interactions rather than long term research projects as I'm not certain of all the lore in play here.
[/quote]I think you interpreted a few things differently here.
Ashtar are still considered an "endgame purpose" as far as advancement is concerned. They also have an aura of mystery around them thus having too much interaction with them would be discouraged.

As for the idea, it can be salvaged. I only mention a suggestion I came up with in a spur so bear that in mind. Draetor are an ancient species doomed to perish. Yet in their plight they were saved by the Ashtar who gave them new semi-ethreal bodies. Consequently you revere the Ashtar as gods and wish to be like them. With your homeworld gone your civilization settled on giant "lifeships" many miles in diameter. Your new ethreal bodies require no food but your souls will erode over the time. To slow this you wear suits to contain your energies and better manage it. In order to replenish you must siphon the souls of the living, a practice you intensely loathe yet begrudgingly perform, never taking it lightly. As "ascended" people you have innate psionic abilities and your technology also use psionics to function.
Bulletpoint changes:
- You didn't work with the Ashtar, they saved you and then went away
- You don't live on one gigantic ship but multiple colony vessels
- Your ethreal bodies bleed away energy fast without their protective suits
- You are in a constant moral struggle over the fact you feed on the souls of others

How does it sound?
