Egregore

This article is a stub. You can help Destinypedia by expanding it.

Egregore is a strange fungus-like life form associated with the Darkness. It has been encountered in various locations like the Derelict, the Cabal Carrier Glykon Volatus and the Leviathan.

Overview

Egregore resembles Earth fungi in many respects, but while Earth fungi feed on dead or decomposing matter, egregore is drawn to the unique psychological phenomena associated with the deaths of sentient beings. The fungus is capable entering the brains of sentient beings through the use of skull-penetrating tendrils, which enable the egregore to suspend the victim's mind in a state of near-brain death, allowing it to feed on the drawn-out death process of the victim.

According to Eris, egregore is a manifestation of Darkness, similar to Stasis, but "impure" in some way. Egregore spores can open one's mind to the Darkness, and also permit affected individuals to pass through energy barriers generated by the fungus. The fungus' mycelial network forms psychic connections between Darkness-associated entities located across space and even in different dimensions, creating links between artifacts of the Black Fleet such as the Pyramids and the Ziggurat, powerful Darkness-aligned beings such as Rhulk and Calus, and the Witness itself. Eris Morn and the Drifter discovered this by experimentally burning egregore stalks near Pyramid technology, which opened up visions of the network formed by the egregore.

Egregore appears to exist in multiple distinct forms, perhaps depending on the environment in which it is found. The egregore aboard the Derelict mostly takes the form of either thin blackish-green tendrils with glowing petal-like tips or amorphous swirling masses, whereas the egregore aboard the Leviathan is gray in color and grows in thick, lumpy stalks. A third variety of egregore has been found growing in the depths of Titan's methane ocean, where it takes on a more coral-like appearance.

History

According to Calus, he first discovered egregore on a distant world, where it grew in great "forests"..

The infestation of egregore aboard the Drifter's Derelict was claimed to have been found on a distant icy world by the Drifter himself..

Presage

As a result of Calus' attempts to commune with the Witness via egregore linked with the Crown of Sorrow, the carrier Glykon Volatus became overrun with egregore..

Season of the Haunted

After returning from the Darkness anomaly located where Mercury once was, Calus' Leviathan reappeared in orbit around the Moon, heavily infested with egregore and overrun with Nightmares. Calus attempted to use the egregore aboard the vessel to form a psychic link between himself and the derelict Pyramid located underneath the Scarlet Keep.

Season of Defiance

The Warlock Druis encountered egregore within the Ascendant Realm while attempting to rescue civilian prisoners from a Shadow Legion outpost.

Season of the Deep

Following Titan's reappearance after having been Taken by the Witness, the Drifter discovered egregore growing in the depths of the moon's methane ocean.

Trivia

• Egregore refers to a concept in Occultism wherein an expressly believed thought manifests amongst a group of like-minded thinkers. The definition of this has changed over time, from manifesting an actual physical being that assists the group, in the form of a guardian angel or other being, to just the ability for the thought to grow in strength within the group, becoming evermore influential in the groups actions. Therefore, egregore is parasitic in its relationship to its host group. This can be said to be represented in Destiny, as egregore has so far appeared to grow within regions of lifeforms with a strong like-minded thought process and purpose; Loyalists and their dedication to Calus, Scorn and their dedication to finding meaning to their existence. Drifter's ownership of some egregore may indicate his singular strength of will to survive, with the egregore feeding on this.
• Egregore is linked to the common theme of memory from other Darkness-based creations, such as the Nightmares and Taken.
