News of the intervention of the Emperor of Water spread through human civilization like wildfire, despite the limited bandwidth for the flow of information between star systems. The information was simply too well-known to possibly be kept hidden. Many pathwalkers and even normal human personnel had felt the unmistakable grandeur of the Water of the Emperor.
It was the same power that they had felt thirteen years ago when he defeated the nebulars that had tried to invade Gaian Civilization and destroy all of humanity. With tens of thousands of people across many spaceships having realized his presence and his intervention, the Gaian Alliance didn't even bother trying to stop the information from flowing.
And so it did, like water.
[I can't believe that the Emperor of Water actually intervened and partook in a battle.]
