What purpose do the Avians themselves serve in society? are they just pampered pets?

I'm just wondering what such a culture even wants in other galaxies.

If they can make energy out of basically nothing (Vacuum energy) and have 'sufficiently advanced technology that's indistinguishable from magic'... what business do they have in screwing around with other galaxies? Don't they have better things to do? I mean, any culture that can do that realizes that the universe is going to suffer from heat-death eventually. If they have effectively unlimited power, why are they wasting time goofing about in the universe instead of fixing the heat death problem?

Thats another valid question, Or dealing with something on a similar scale, I think the "Xeelee" are a good example of an Intergalactic civilization done well.
