Nathan had been observing this whole time because he had a lot to think about. As expected, it looked like there was no other choice but to kill the singularity.
Nathan had roughly grasped the power level. The world class summoners were nowhere near Cthulhu's level. However, Fenrir, who was known to be able to go to outer space to swallow the sun, should be considered a solar system level power.
However, those who had gone beyond that level would be considered a galaxy level power. They could travel freely around the galaxy or even visit another galaxy. It was no wonder that the aliens were talking about places so far away.
Nathan never expected the true gods to be at this level. Still, it made some sense. This might be the reason Zeus was said to be scared of Nyx. Nyx could simply whoop his ass if she wanted.
And the alien's Outer Gods were at this level or even higher. And at the peak was Azathoth and the singularity.
