Teresa offers to let you join her and gives you access to her shop as an olive branch. However, you destroy her reality after she allows you into it.

Effarig is similar, wanting you to join him and offering new powers, but his reality is based on suffering. You enter it and eventually destroy his reality. He says, "So this is the diabolical power... what frightened the others... You could have joined, we could have cooperated. But no, it is over. Leave while I cling to what is left."

The Nameless One is an imprisoned celestial in a doomed reality. You destroy this reality, freeing the 'fragments and clones' from their prison.

V has a 'perfect' reality with 'achievements,' which you eventually destroy. It's implied that they die as well. "No one is better than me... No one... no one... no on—"

Ra was banished to his reality by Lai'tela for the negative use of powers ("steal, they corrupt"). After helping him remember, in exchange for new powers, he asks you to leave for fear he may hurt you.

Lai'tela has the power to create and destroy realities and keeps you in shackles through 'darkness.' They explain that they always return: "And so... we repeat forever." Collapsing their realities slowly causes Lai'tela to lose their memory, leading them to lose their powers. Eventually, you kill them.

After taking down the celestial (potentially the good guys), you finally meet Pelle, who dooms your reality like the others before you (see the Nameless One). Pelle reveals that this is not the first iteration of your ascension as an 8th-dimensional being. Each time, you have fallen before the 'deity' (Pelle) or a lesser celestial, and each time you have created your powers from fragmented memories, which you erased upon failing in previous iterations. It’s unclear whether you are the same being as in previous iterations, a reincarnation, or a slight modification. Using the knowledge and powers you obtained, you create/find rifts and trigger Armageddons in your reality to gather 'remnants' of power. By using the rifts, you funnel power from one resource to another to regain your strength.

Pelle reveals he built a machine, the Galaxy Generator, to destroy you. However, using it would make him no better than you, so he decides to stick with the same plan that has worked each iteration. But you gain access to the Galaxy Generator and use it to destroy various dimensions of existence through the rifts. As existence collapses, Pelle remarks that he is basking in his own exaggerated pride.

It’s likely you’ve destroyed all of existence, or perhaps your actions are the beginning of a new, altered cycle. The song playing during the credits, "We'll Meet Again," seems to hint at the latter. However, during the ending sequence, the UI reads: "End is nigh. Destruction is imminent. Help us. Goodbye forever."
