Worm

"Take into your bodies our children, our newborn larvae. From them you shall obtain eternal life. From them you shall gain power over your own fragile flesh: the power to make of it as you will. And should you find an imperfection in the world, an injustice or an inconvenience — you will have the power to repair it. Let no mere law bind you."

- Yul

The Worms are an ancient, parasitic worm-like species that dwelled deep under the oceans of the gas giant Fundament. They are disciples of the Darkness and draw their god-like power directly from it. It is through a pact with the Worms that the ancestors of the Hive became the Hive and launched their conquest of the whole universe. The Worms are worshipped and revered as the Hive's highest deities, beyond even Oryx, the Taken King and his sisters Savathûn and Xivu Arath. All Hive are infested with a larvae from one of the five Worm Gods, which drives them to feed off constant conquest and destruction lest the Worm grow unsatisfied and consume them instead.

Worms are notable for their ability to survive death in some form, similarly to Ahamkara. Despite calling themselves worms, the Worm Gods describe themselves as having jaws and wings, and that they are of massive size and strength.

History
Billions of years ago, the Worm Gods were trapped deep beneath Fundament and guarded by the Leviathan. One of their dead larvae eventually washed up on the shore of the Osmium Court, where it was found by the proto-Hive Osmium King and taken as his familiar. Following the Osmium King's murder by the Helium Drinkers, his daughter Sathona took it from him as she, Aurash, and Xi Ro fled the Court. The dead worm spoke to Sathona, and through her guided the three sisters in their quest for vengeance.

Eventually, the worm led the sisters into the depths of Fundament, to the domain of the Worm Gods, who tempted them with power and immortality in exchange for becoming parasitized by their larvae. The sisters accepted, taking on the names Auryx, Savathûn, and Xivu Arath. Acting in concert with the Worm Gods, they took more larvae back to the surface in order to offer the rest of their species the same bargain. Those who refused to accept were killed by the emergent Hive.

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. The Hive eventually exterminated the Ammonite and slew the Leviathan. Eir and Yul consumed their captor's corpse. After this, the Worm Gods withdrew to the Ascendant Realm and generally left the Hive alone.

Auryx would later seek out and slay Akka for the knowledge to commune directly with the Darkness. He returned as Oryx, the Taken King. However, Akka remained active in some fashion and battled Oryx following the events of the Golden Amputation. At some point Oryx recovered a fragment of Akka's shell and used it to craft his Dreadnaught.

Some time after the death of Akka, Yul began to contemplate taking the power from the weakest of the four remaining Worms, in order to withstand any future attacks by Oryx. Knowing himself to be vulnerable, Xol, Will of the Thousands made a pact with Oryx's abandoned son, Nokris, to flee Fundament and seek new worlds to conquer together.

A long-standing Vex incursion in Oryx's throne world eventually drew the attention of the Worm Gods. Eir commanded him to "SET YOUR HOUSE IN ORDER".

Many years later, upon the frozen ice caps of Mars, Xol's physical form would perish at the hands of the Guardians, along with his herald. As with Akka before him, Xol survived his death in some form, and would go on to present himself to a group of Taken on Io, who offered him worship and service.

Biology
The Worms are a parasitic species, entering into symbiotic relationships with other sentient races in order to amass greater power for themselves. As larvae, they can inhabit the bodies of other beings, such as those of their servant race the Hive, and "feed" off the power acquired by their hosts through following the Sword-Logic. Worm larvae are pale and about a meter in length, with rounded heads, six short spines on their back, and two spines at the end of their tail.

As adults, Worms can reach tremendous size; Xol, the first of the five Worm Gods encountered by the Guardians, was hundreds of meters in length, and the size of the Dreadnaught suggests that Akka (one of whose segments was used by Oryx to craft his flagship) was orders of magnitude larger. Fully grown Worms are covered with segmented plates and numerous spines, and have heads with six barbed mandibles surrounding glowing eye-like structures.

Notably, the Worm God Yul describes himself as having wings, while Xol is not seen to possess wings when encountered on Mars. This may suggest that only the largest and most powerful Worms possess wings, as Xol is implied to have been the least powerful of the Worm Gods.
