But wouldn't you say the Sages having such a power and choosing not to use it would fall under an "invisible event", such as what you accused me of? Not to mention the whole "intent" argument that people love to get into around here. And unlike the "Divine Prank" stuff, this really has nothing for or against it, aside from the aforementioned "Do's and Don'ts of timeline theorizing". Not to be accusatory, I'm just a little confused.
An "invisible event", as I referred to earlier, is an event that we are supposed to believe took place, yet there is no actual reference to it. For example, there is no reference to Ganondorf enterring the Sacred Realm in the Child Timeline, so it is an invisible event.
As for my current argument, I'm not trying to suggest specifically that the Sages are choosing not to use an invisible power. I'm arguing that the Sages did not confirm that the power balance was in their favour, and thus their perceived ability to control Ganondorf's evil magic was an overestimation. The Sages didn't need to search specifically for the Triforce of Power; they just needed to make sure that Ganondorf's evil magic was properly subdued, and it wasn't because the Triforce of Power had increased it beyond the expected proportion.
