The system's entire story introduction actually had a narrative subject: the group of wizards who sealed the "eye."
From that narrative subject's perspective, those wizards seemed like pure victims. They discovered that they were being pursued by the eye, found a way to carve down the eye and end the pursuit, and were then discovered by the eyes behind the other wizards.
But what if those wizards were not purely victims?
What if, throughout the whole story, the "wizards" had been the active party?
The Eye of Truth did indeed pursue wizards seeking truth, so some bold wizards wanted to capture the Eye of Truth following behind them.
They shared this plan with other wizards, but it was not accepted, so they decided to do it themselves.
