The wait wasn't too boring.
Pello fought a brilliant battle.
Unable to push the front line to the Chaos Lord's doorstep, Pello held the line while Horus and Utu successfully converted the suns in the Chaos galaxy into their own divine power sources.
It turned out that the Chaos forces had no good answer for stars. No matter how strong Chaos's pollution was, it couldn't withstand extremely high temperatures. This was especially true since the star in the Chaos Mother Star's galaxy was a red star with a surface temperature of 30,000 degrees Celsius.
In comparison, the Sun's surface temperature is about 5,500 degrees Celsius, and its core temperature reaches 15 million degrees Celsius. (The surface temperature of stars can vary greatly. For example, yellow stars like the Sun can have surface temperatures up to 5 million degrees Celsius.)
Thus, Pello's God of Light pantheon now possessed two suns: the Chaos World's sun and the Chaos Mother Star's sun. Pello took about 60% of the power as divine power, with Horus and Utu each taking 20%.
The God of Light pantheon thus became a top-tier pantheon with three powerful divine power deities.
With the support of the local star, Pello continued to hold the front line, allowing Horus to elevate his divine kingdom to near-Earth orbit around the Chaos Mother Star and begin purifying its atmosphere.
This move infuriated the Great One.
"Bastard, bastard, bastard!" The Great One killed countless unlucky Chaos Devils in a fit of rage.
Before, Pello hadn't wanted to do this, but he was spread too thin.
As the core of resistance against Chaos, Pello could use his divine power to purify the front lines, leaving him no time to convert the Chaos Mother Star's sun. If he converted the sun, he couldn't hold the front
