When Aether handed the money to the Archpriestess, he did it with a deliberate purpose, driven by two distinct reasons.
First, the obvious one: he had a strong displeasure at how he had acquired the money and..... yet to notify Lia.
Second, it was a test... a crucial experiment.
For his Ethereal Domain, it was essential to aid the pure beings who were in dire need of assistance.
The first thought that came to his mind was the orphanage.
The orphanage was a place filled with pure beings, children, who were innocent and in desperate need of support. They were the embodiment of purity, untouched by the corruption and complexities of the adult world.
So, he decided to give the money to the Archpriestess, hoping it would find its way to the orphanage. He wanted to see if there was a possibility that this money would truly help the children in need in their lives.
