When a magical being named the Rectifier comes through, the Adapter knows he has more power than the Illuminators, the group of divine beings with the power of light who usually fight evil that are struggling to stop the Disrupter gaining the power he needs to destroy Omnipion.
The problem? Not only does this Rectifier not want to fight the Disrupter, he almost agrees with her that the game of life she created for sentient beings to test themselves is unfair to evil players. He also wants her to go to earth with him, to be his human mother, so she can compromise and change the rules, which is exactly what the Disrupter wanted in the first place, and what they were fighting against.
The Adapter wanted to create Omnipion as a gateway for beings to experience physical life, with the condition they test themselves with the trials and tribulations one would create for them. They all agreed, if their true natures turned out to be evil, they shouldn't return to the perfect realms above.
Once they became so evil, and were about to get used up as fuel, however, most of them would rebel, claiming their true selves weren't as dark as the game had made them, stifling the flow of Omnipion's inner levels.
It's only after a being from the supportive forces, a realm that sees good and evil as subjective, comes to tell her the game of life that she created wasn't fair to evil beings, that everything changes. This being, who she names the Disrupter, confirms that the beings she's deemed evil, which she would destroy if they weren't rebelling, weren't really dark. She says it's her game that's tarnished them and, even if they failed the test, they'd go back to the realms above untarnished; just more learned and experienced.
The Adapter makes a deal; if the Disrupter goes into the game, and proves that the beings Omnipion deems evil can be redeemed, she will change the rules to destroy them. 
The Disrupter accepts the challenge, but warns if she hasn't changed the rules by the time her one thousand lifetimes were over, she will destroy Omnipion.
The Disrupter proves a few humans can be redeemed, but not all, leaving the Adapter unable to produce the power it takes to change the rules, giving the Disrupter the go ahead to collect the abilities she needs to destroy their world.
The Illuminators fought against the Disrupter, trying to stop her from gaining the power to do so, but she was becoming too strong. It's only when she has one more ability to collect that another being from the supportive forces comes through, who wants to help save all the good beings in the test who wish to continue playing the game.
The problem with this saviour, who she names the Rectifier? 
He doesn't have the heart, or inclination, to fight the Disrupter!
He also argues some of the same things the Disrupter argued, claiming that she must have a first-hand experience of a biological life, to understand how adverse situations can break a beings spirit to produce the power she needs to change the rules. He says in case his passive ways don't work, she needs to convince him that fighting is his only choice left, insisting she must go now, before it's too late.
But was going to earth really the only thing left she could do to help save the world she created? Worse still, could she go, knowing she may learn she'd been wrong all along? How could she leave her realm, and all the sentient beings who rely upon her for their pre-life training?
One thing was clear, if she didn't go now, it was likely she'd have no beings left to ever train again.
