"Oh. An interesting coincidence." Pop nodded, but then added, "No, that is not the reason. Sword and Shield are in fact perfect candidates for this power, for a few reasons. The first is that they have experience, even partially, against Dark Matter, but are not of my world, which required a more rigorous process for Ascention. But if they are not of my world, I can more readily make temporary Ascensions for the time being. What happens with them afterward is... less a concern, because if all goes well, they will leave Cibus and return to Telum, and my power in that domain will be much weaker. There is less long-term risk.
"They also both have some experience with Eterna energy already. Sword, as you've all seen, and Shield, who freed her. They know what the energy feels like and how to fight against it. And, as for your concerns with Sword specifically... I have done extensive evaluation on her psychology at this point with the help of Breaker, Wheat, Bean, and even Fugu, as well as other top psychologists to make sure she can be trusted with this power.
"On the surface, her Darkwhite persona appears to be just as unstable as before. But closer inspection reveals that Sword is perfectly in control of this power, at least insofar as not harming others with it. She may be a... showboat and a braggart, but she does not unnecessarily use her power any longer." Pop nodded. "I was skeptical as well... but the evaluations were consistent. She is stable."
