A Proxy
Ryu didn't know what was going on in the outside world, but he certainly had a few guesses about how that might go.
Now that the Ruin Master Guild wasn't directly involved, he could see the Fate Lines of the future with added clarity, so the movements of the Dao God could be fairly well predicted by him.
Of course, these were all probabilities and not certainties. Thanks to the unruly laws of math, even if he had 90% assurance on every prediction he made, if enough stacked up, he would have less than a 1% assurance in guessing anything.
It didn't even particularly take that many variables. A 90% assurance in guessing 44 things in a row would mean that the odds that he would be correct about all of those things would be less than 1%.
That said, the odds that he would be incorrect about all of them would be even less than that by a large margin. However, that hardly mattered when he was trying to guess at things so far into the future.
