Summary[]
Link and Zelda wish back Lorule's Triforce with their own, which instantly starts restoring their Sacred Realm and soon, Lorule. The restoration spreads over the solar system or universe sized Sacred Realm by the time Hilda, the reverse-Zelda can thank the two, as Lorule already being restored before that. I will only be calculating a high interpretation of it, as I highly doubt this calc will be accepted, and this is purely for fun.
Before one says that the skies look the same so the Sacred Realm is a part of Hyrule, it's been claimed many times that it's an alternate reality, and the fact that the Dark World is a corrupted Sacred Realm and has the opposite of all of Hyrule's stuff speaks volumes.
Calculation[]
Size of a universe is 93 billion light years.
Assumed timeframe will be 3 seconds. Doesn't take too long to start saying thank you.
978,302,634,500,364,900 c. That's the restoration speed of the TF
Scales to Moblins :P
