This hinges upon whether or not the “pyramid ships” – or Dark Travelers – follow the Sword Logic. Yes, the Sword Logic is a valid philosophy and is backed with power, but consider: we’ve only seen it through the lens of the Hive, a species driven to eventual self-extinction because of their parasitical pact with the Worm gods.
After all, the Sword Logic demands you take to grow strong, and those who are weak are doomed to die. The Hive were duped into accepting the worm larvae, meaning they were in ignorance of the Sword Logic until it was too late, and they were already enslaved to those who followed it more perfectly than they.
Yes, Akka was killed by Oryx so he could learn how to Take wills, but the Worm gods – while approving of Oryx’s feat – don’t seem to war on one another regularly like the Hive do. They are just content to laze around and eat all of the Hive tribute.
This means that they have understood the Deep’s philosophy than did the Hive. Because if you immediately took the Deep’s power for yourself, you are above reproach unless a stronger than you takes it from you. But what if you were the only strong one because you were never duped into accepting a gift worm in the first place? The Hive, as said before, are doomed to self extinction by their own admission. The Worm gods do not care if they die, they’re just exploiting them as warriors and meat shields to carry on the Darkness’ crusade to forge life into the perfect sword. They just want to be the final form of that sword in the end.
What if these pyramid ships were already this perfect sword, because they alone dictate the rules of the game, blessed by the Darkness because they have proven to it they were worthy because they usurped its own power? (Kind of a bizarre way of looking at things but bear with me.)
As Oryx says from his discoveries about the Darkness:
The Deep doesn’t want everything to be the same: it wants life, strong life, life that lives free without the need for a habitat of games to insulate it from reality.
If everything were doomed to be like the Hive, that would be anathema to the Deep. The Worms themselves know it, because they are not like the Hive, but are more closer in understanding the Deep and its ways.
The Deep is looking to craft the perfect sword. The Hive are a means to this end, but they are ultimately destined to be cut apart unless they figure out how to usurp the Worm gods entirely and free themselves from the pact. The Worm gods are also a means to this end, and they may become that sword.
What if the pyramid ships are already the perfect sword, forever honing itself against all lesser things until nothing remains? What if they were, because they were not like the Hive? They possess the Deep’s power – they can “gift” it to other civilizations if they want, like the Worms did with their larvae to the proto-Hive, and then kill them in the end because even these “gifts” were a means to that one end.
The point is – if they have already “taken” the power, then what’s to stop them from using it however they life?
