A black hole thing was created by an alien species and it inhabits a whole world in it that can fulfill a person's desires through the manipulation of space-time or creating multiple dimension layers. I forget the specifics, but it basically requires a lot of energy to run. This creates a black whole phenomenon, where it engulfs all the energy around it to feed whatever the person inside it has imagined. Essentially they get telekinetic powers (or mind bending reality powers of some sort).
A space exploration ships gets engulfed inside this black hole and I remember there being two planets that one of each ship crash lands on. They can't use their technology because it seems to go haywire in this world, and there are these monster things that are already there that seem to take over a organism's mind, that they have to fight against.
I don't quite remember what happens with one of the planets, but on the other planet, they get everything figured out and establish a civilization of sorts with telekinetic powers and a force to fight against these parasite things. On comes this villager guy, who turns out has extraordinary telekinetic powers and can do lots of things that amaze other people. He becomes a legend, basically Hercules, but with telekinetic powers.
The story reveals that the really strong guy had powers so strong he sent out his entire life in memory to the outside world, which some guy on the other end receives and becomes some sort of messiah, and they start a religion out of it because they want to travel to this world since they think it's some sort of tangible heaven.
There's obviously a lot more to this as it is a book series, but I think I gave enough of a intro and my memory of this series is all over the place, but I hope someone can point me in the right direction because it was a good book series that I'm thinking about reading again.
