anyone who's read enough about the origins of the hive, the fundament gas giant/ocean world from which they came, notes that the traveller was likely orchestrating the numerous moons around the gas planet into symetry to organize a god wave, in which to crush the worms at the centre of the deep, but was deterred by aurash and her sisters finding the worms and the ensuing battle.
something i recently noticed, not while reading specifically about destiny, but rather about some noticed seismic waves that are actually happening on saturn, (lots of interesting science there, actually), is that the planet has 62 moons. interesting parrallels there with a theory out there that numerous gas planets were seeded originally with these worms, that may have bargained symbiosis with the ahamkara, and obviously the hive.
things to think about, as to why oryx showed up and stopped precisely in saturns belt.

Bungie has a huge habit of splicing in parallels from other games, and in my opinion Destiny resembles Marathon more so than any other title. My theory of the Fundament comes from this, and the way the theory goes is that an ancient race (or someone/thing) trapped the worms in a gravity prison, some sort of manufactured singularity, and the Fundament is a collection of worlds trapped in its pull, where Oryx's race, among others, lived. The grimoire entries use a lot of metaphor, so "the Sea" could be the ruin of a solar system, filled with the debris of broken worlds and civilizations swirling just outside of an event horizon. Oh what the Hive, and their three eyes must have seen...or is it Pfhor? =)
