The Pill Clouds were a manifestation of the Heaven, so theirs was the only authority it accepted.
However, because the Heaven itself was a manifestation of the Intent of the two True Gods, they could use that connection to provide their authority to the Pill Clouds. That way, they had a say in what the Pill Clouds did.
Alex could tell that the Heavens were trying to relinquish their control over the Pill Clouds, but failing to do so each time because he couldn't create a proper connection. There was some sort of barrier stopping it from happening, which Alex understood to be his seal around the Sun God.
It made him realize that he was as close to a Sun God as he could possibly be without actually being him. Had he been the Sun God, he wondered just how much easier it would've been to form this Creation.
Thankfully, what he had gained was more than enough for him to start learning more about the Pill Clouds.
