Gary Smith's Eye of Truth was linked not to a typical pupil skill displaying information but to the "Master of the Gate" [Taboo Position].
The source of his power stemmed from the Key of Truth and the "Gate." In theory, as long as Gary Smith had enough spiritual power, he could see all information.
This meant that the past, present, and future were all inclusive, covering everything that existed or didn't exist—as long as it was correct, it fell within the realm of truth!
Of course, if the difference was too great and the secret itself contained danger, like the Arcane God, who mastered the concept of secrets.
Or it could easily attract some great horrors
It might drag the whole Main World down with it!
This spiritual power restriction was actually a form of protection for Gary Smith, given that in his previous life he ended up splitting up from his group because he was unable to receive information!
