Chen Yi had thought of two possibilities. First, Aurelion Sol was not unique; there were multiple of him.
Second...
Creation was an opportunity. A naturally born Creator God possessed authority and had no need to deliberately seek opportunities.
But no Creator God would create worlds without end.
Without causing a qualitative change, no amount of quantity would matter.
If he was willing, then it did not matter.
The problem was that, judging from Ryze's introduction, it was not as simple as ten or eight worlds.
Creating worlds required consumption, and that cost could only have been paid by Aurelion Sol.
Looking at it from another angle;
A group of Heavenly Beings had used World Runes to create Runeterra, a connection point between worlds. Then was the creation of those other worlds truly Aurelion Sol's intention?
Everyone believed Aurelion Sol had a collector's obsession.
He did not want Runeterra destroyed, which was why the Aspects had restrained him with a crown.
If the information Ryze brought was true.
Could it also be understood as;
Aurelion Sol was unable to stop other worlds from appearing, and his power had already been divided up.
Perhaps Runeterra was currently the only thing maintaining the connection between his powers.
Once Runeterra was destroyed and that connection point vanished, the other worlds would separate.
By then, whether this Creator God could still maintain his own power would be hard to say.
Only this could reasonably explain why this Creator God loved Runeterra so much, even allowing himself to be suppressed by a group of Aspects who were like ants to him.
Chen Yi leaned more toward the second guess because there was evidence to support it.
Runeterra's law suppression was the best proof.
No other place had it. Only Runeterra did. It was practically a law
