Charlotte realized she had always overlooked an issue.
In Mireya's world, high-order Transcendents were by default not allowed to actively participate in frontal battlefields or massacre mortals, which had almost become humanity's most famous acknowledged "rule" since the Holy Era.
However, not being allowed to actively participate in the front lines did not mean high-order Transcendents could not intervene in wars at all.
Indeed, if high-order Transcendents couldn't even protect their own affiliated powers, then what was the purpose of their existence?
The high-order Transcendents who formulated such war rules, how could they agree to a "rule" that disadvantaged them?
Correct.
Not being allowed to participate actively on the front lines did not actually mean they could not participate passively.
For example... maintaining a large-scale Magic Defense System.
