The Tide is what the Frontier calls the Alien Hive: the oldest power in the universe, and the only one in the Frontier that is not human. No commander has ever flown for it. No commander ever will. It does not recruit, negotiate, surrender or explain itself. It harvests.
It took the Cradle, humanity's homeworld, and drove the survivors into the Long Dark. It has harvested an unknown number of civilisations before that, whose remains lie scattered across the Frontier as artifacts. In 371 AL it found humanity again, broke the Iron Vanguard at the Grey Verge, and took the Rim. Then it stopped, and it has been growing there ever since.
“Every other enemy in this war wants something you can understand. That is how you know the Tide is different.”
— Fleet Admiral Selene Voss
