>>55011777Yep, the Paradox Book and the Occulture are the equivalent of the Murals in TotK. The murals depict all the events that you learn occurred, and by the end of the game you realize that it's telling the story of Zelda being sent back moments after they first discovered them.
It's a temporal paradox with no true beginning, because it only happens because Zelda is thrown thousands of years into the past. That leaves the question of how do the murals originally exist? The game never explains this to you, and the Indigo Disk will probably present a similar scenario. This is why Khu backtracked saying that "they won't explain it" because it's a paradoxical loop that doesn't have an explanation.
