Akka, the Worm of Secrets

"Akka my God, Worm of Secrets. I am Auryx, sole king of the Hive. I have come to receive a secret. I want the secret power of the Deep, which you hold"

- Oryx, the Taken King

Akka, the Worm of Secrets was one of the five Worm Gods, ancient beings second only to the Darkness itself in the hierarchy of the Hive pantheon.

Biography
Billions of years ago, Akka and the other the Worm Gods were trapped deep beneath Fundament and guarded by the Leviathan. The Worm Gods oversaw the Hive's conquest of Fundament, providing knowledge, orders, and censure to their leaders as necessary. When the war freed the Worm Gods from Fundament's core, they responded by opening a wormhole into geostationary orbit, allowing the Hive to invade Fundament's moons and the Ammonite civilization that dwelled there.

Auryx, the King of the Hive, seeking to gain the power to feed his worm, traveled the Ascendant realm in search of Akka. Akka and Auryx spoke of the power of the Deep, and since their power was gifted, and not taken, it was not true to the Deep. Auryx attacked Akka and slew him, then communed with the Deep himself. When he was finished he crafted the Tablets of Ruin, gaining the power to Take and becoming Oryx, the Taken King. Though dead, Akka was not gone, and Oryx was forced to battle his god's "swarming corpse" while escaping his sisters' treachery years later. Oryx used part of Akka's body to craft his Dreadnaught, a massive ship in which to house his Throne world. Billions of years later, Akka's name has fallen into near obscurity, as Toland, the Shattered had only the faintest idea of his existence, but not his name.

Trivia

 * Verse 3.8 of the Books of Sorrow seems to imply that some of Akka's paracausal powers are ontological in nature: when he is confronted by Oryx, Akka is said to have been "denying a truth until it became a lie," and was afraid to deny the truth of Oryx's words lest "the truth might become false."
 * Therefore, when Akka denied that Oryx had the strength to slay him, he may have inadvertently sealed his own demise.
 * Based off the art of Oryx facing off against Akka, he may be immensely bigger than Xol
