The "angels" of the Sun God System were actually Gods. Every time He conquered another God, He would strip that God of their clergy. But He would allow them to continue hosting related matters. He would turn them into His believers in the faith transfer station and named them beautifully, "angels."
The powers of these angels were naturally lower compared to when they were still Gods, but their basic powers were still there. There was not much loss in combat power either. As long as the Sun God did not directly take over the faith that they were responsible for, they could still battle.
Among these angels, the few who were strongest had medium-divine powers before turning. So even though their powers were indeed lessened, they were still at a similar level.
There were a total of four angels like this, and they were called the Four Main Angels under the God of Glory.
