Is that Arya Stark?

is that not just what a giant cluster of galaxies is? but if you mean why there isn't a giant sun and galaxies orbiting it, probably because those bodies would have to be bigger than anything we've ever seen.

We are too far past the stage of tiny galaxy clusters mashing together. Now all we have to look forward to is BIG galaxies crashing into each other...
Which thanks to relativistic time means it takes forever.

So, in billion years in the future such galaxies will form. But weren't scientist saying that due to space expansion distance between galaxies was increasing?

There ARE galaxies made of galaxies. In fact, our entire galaxy is made of exactly one galaxy, and there are two galaxies that orbit our galaxy, though we just call them Magellanic clouds..
