I imagine they exist in massive ships, having used up all the resources from the home planet below.
Such advance aliens would perhaps have become no match for us looking to conquer and colonize whatever planets they can reached.
If so, it make sense for them to exploit new planets to build more spaceships so they could move on. Who knows what the limit would be.Perhaps, their capabilities will only be limited by how much power they could harness and control. And that would be far more than we might first imagine.
For example, it might be possible to collect the energy from an entire star. To do that, they could deploy millions of mirrors in space encircling the whole sun and feeding the power to one single collection point. Such power might be possible to work the very fabric of space and creates a hole called a wormhole. This portal would act as a shortcut allowing them to travel huge distances in a blink of an eye.
Like us, they would probably have a vault from species used to expoiting whatever it can.
