This civilization is a combination of the powers of the civilizations of The Downstreamers/Old Ones, The Xeelee, Humanity (Xeelee Sequence), and The Beyonders, in addition to the powers of Doctor Manhattan, and the use of technologies: Bundectotechnology and Metareality engineering, which are fused within their own existence, making these technologies their own existence and their existence be technology itself.
With this, you have become an incorporeal being, in which it only exists through your consciousness, physical bodies are no longer needed and are just mere avatars to manifest your being. They are eternal beings, or you could say that they have surpassed the existence itself, they have been looking for many ways, but nothing has been able to eliminate them, not even themselves, that is, to become one of them, means that you will never cease to exist and cannot be a normal human again.
As a chosen to be part of such a civilization, you have a duty to protect all existence by eliminating integer races, civilizations or universes that represent a threat to every existence, as well as creating new substitute universes and ensuring their functioning. Other than that, you can live as you want, always remembering to maintain your responsibilities and duties with existence. But to live with lower civilizations, you would have to create your avatar, to ensure that your existence does not destroy that world. Their 3 main objectives are:
Observe the evolution of each civilization, analyzing how they evolve their science and technology, ensuring the evolution of some civilizations they approved are worthy.
Choose some civilizations or individuals to be part of your race.
Entertain themselves and have fun with the infinite multiverses, whether they just watch, or even interact and manifest in different ways.
After this civilization explains all this:
Would you accept to be part of them?
Case yes:
How would you "live your new life"?
Would you create new universes for you to rule?
Would you live traveling from universe in universe or choose one to spend most of the time?
Would you interact more in universes through your royal manifestation, playing God for other civilizations, or would you use your avatar more to live among them?
What would be your action if a universe in which you lived longer, was chosen to be deleted?
If you were given permission, would you gather two or more universes in one? What would be the reason to gather them?
Over time, would you choose other individuals or civilizations to become transcendental beings like you?
Case no:
What was the main reason for the refusal?
If you were given your chance to receive some powers and be a herald of them, would you accept?
What powers would you choose to have?
Would you keep your human life time or extend it? If it were to extend, how old would you choose to live?
At some point, could there be a chance for you to go back and decide to become one of them permanently?
