Percy's plan was simple in essence, they always were, but where the problem came was implementation.
For a long time, he just stood there, calculating using his system, meditating, and using the spirits to recall memories, a trick he learned a couple of years ago.
With this, he was able to cycle through all his memories of hermetic materials and circles.
The plan was to create a new Spellcore here and now with his customizable rewards, then use it to take control of the entire temple. This was based on his understanding of how this temple's main circle worked.
It needed someone at the center of the circle to draw on its full power—a human being at the interface between the energy and the casting of spells. And it was all done by the special circle drawn here that allowed a spirit to share a human's intelligence.
