[spoiler]So let's sum those 2 up. The Vex created a machine, named Quria, Sword Transform. Quria was tasked with finding out Oyrx's secrets and destroying him. It got into his Throne World and captured some Worm Larve. It then commanded its sub minds to worship the larve to learn their secrets.[/spoiler] Ooh! Good connection. It's been so long since I've been into the Black Garden that I'd totally forgotten about its Heart. It makes perfect sense, the Sol divisive protecting the Heart appear to be incredibly old, and the Books of Sorrow explain that the capture of the Larvae took place some thousands of years ago. Overall I think the theory is solid, except for the part about the Ahamkara. While Akka may have "great and coiling length ... folded jaws and curled wings." it does not make him an Ahamkara. If you remember, Oryx simply [b]decided[/b] to grow wings one day. I imagine, with the seemingly unlimited power granted by The Deep (The one who fuels the Worm Gods and their Larvae) Host species would have the ability to transform their shapes at will.
