Universe spanning empire from the dawn of the universe(measuring milliseconds from the big bang) with an FTL drive system which is intrinsically a time machine(10k lightyear jumps ariving 5 years before you left in about Planck’s time? Can do). Their history is a temporal loop spanning over 5 billion years and has and always will exist. Thye have no beginning and have no end, and emerged fully formed into the universe a very short time after the big bang.
The Xeelee are composed of a symbosis of 3 different sentient species. The 1st and oldest is a form of creature which is composed of spacetime defects, they are living pockets of spacetime were the laws of spacetime are different. (IIRC)The 2nd is composed of quantum wave functions which can send information down a quantum inseperatable link effectively instantly(sure as hell isnt limited by the normal speed of light). The 3rd is some carbon base lifeform.
They constructed the great Attractor for their universe and move so much mass it is the literial centre of mass of their universe. This Great Attractor is constructed out of super-strings rotating at near c, and in some locations greater than c relative to other portions of the Ring.
The purpose of this great Ring is to escape the universe, as the Xeelee have been fighting a losing battle against Dark Matter creatures which only loosly interacte with normal matter.
I believe, based on the latest Xeelee books, that the Ring is more than an inter-universe transportation system. It makes no sense to expand so much effort when technology demonstarted in Xeelee-verse can more easily cross into alternitive dimensions. (Reality Dust is a good case for this). I believe the great Ring actually generates universes based on a criteria.
Xeelee-verse universe's are created by some truely alien creatures which only exist as defined by their relations with others. They like universes with stories, thus the universes they create are filled with life. Given that it is posible to interact with them via super-massive blackholes(they exist in the Singularity?) it stands to reason that the Xeelee have learn how to interact with them to the nth degree. And they have the perfect tool todo so, the entire purpose of the great Attactor is to create a naked Singularity.
Thus the Xeelee are creating their own designed universes.
