The Lunar Pyramid

"Violence. Beauty. Truth. These things await inside."

- Ghost, seemingly possessed by the Witness.

The Lunar Pyramid is a Pyramid located below the surface of the Moon and the source of the Nightmares that plagued it. This Pyramid was once a part the Black Fleet that attacked the Sol System during the Collapse, only to be left behind centuries later until its discovery by Eris Morn reawakened it.

Overview and layout
The outside of the Pyramid's hull is covered in segmented panels that vary in pattern, with some having vertical lines and others with patterns resembling circuitry. Much like the Traveler, the surfaces of the Pyramid seem to be composed of some form of rock-like material, occasionally having an uneven or chiselled appearance, giving the ship an almost handcrafted quality.

The Pyramid can be accessed by an opening on one of its upward-facing sides; this opening can produce a tractor beam to bring objects or visitors inside. The interior of the Pyramid appears to have been designed with human-scale inhabitants in mind and contains many hallways, stairways, and various open spaces. Many parts of the architecture feature subtle gold ornamentation or chiselled, seemingly abstract patterns. It is dimly lit, with occasional harsh white or red lighting providing the only illumination. Small container-like objects can be found scattered around the halls.

Among the most notable objects found within the pyramid is a massive sculpture, apparently of a humanoid figure draped in what appears to be a veil or shroud. It is currently unknown what this sculpture represents. However, a nearly identical one appears in the Black Garden, watched over by a Pyramid Scale and the Sanctified Mind, Sol Inherent.

Shadowkeep
"Welcome. We've been waiting."

- Ghost, while possessed by the Pyramid.

The Hive under Crota, Son of Oryx were the first to discover the inactive Pyramid beneath the Moon centuries after the Collapse which lead them to embed themselves into the planetoid as a War moon. It is implied by Toland that the Hive had studied the dormant structure and failed to awaken it countless times before the events of Shadowkeep.

Under the leadership of the Daughters of Crota, the Hive built a Scarlet Keep near the Pyramid's location that could amplify their magics, harness the phantasmal essence of the Pyramid and immunize themselves of its influence. In addition, the Daughters attempted to use the Nightmare essence to recreate Oryx, the Taken King and their father Crota to no avail.

The Pyramid was discovered by Eris Morn following the Red War and the events of Forsaken. Upon touching its surface, Eris triggered a seismic disturbance, revealing the Pyramid in its crevasse. Having awakened by Eris, the sudden release of the Pyramid's potent energies levelled the terrain of the Ocean of Storms and subsequently brought Nightmares in the form of phantoms, which haunted the surrounding caverns and lunar surface.

The Hive of the Hidden Swarm saw a prime opportunity in the Pyramid's sudden appearance and of its phantasmal creations. Under the leadership of the Daughters of Crota, the Hive began summoning Nightmares near the Keep starting with the Nightmare of Gothrax, Swarm Protector and the Nightmare of Arguth, the Tormented. Eventually, they began to summon Nightmares en masse and sacrifice them to reap their phantasmal essence to empower Zulmak, Instrument of Torment; a hybrid Hive-Nightmare abomination to serve as the Daughters' puppet champion.

After crafting a set of Dreambane Armor with the aid of Eris Morn, the Guardian was able to approach the Pyramid, which produced a tractor beam to draw the Guardian inside. Within the Pyramid, the Guardian faced Nightmares of Ghaul, Fikrul, and Crota. The Guardian's Ghost was seemingly possessed by the Darkness during this period and commented on the weakness and failures of the Light. After slaying the Nightmare of Crota, the Guardian was guided to a statue of a veiled figure with an unknown artifact placed before it. The Guardian hallucinated themself in the Black Garden, where a doppelganger with a sinister smile spoke on behalf of the Pyramid.

Sometime later in the season, Eris herself would personally step into the Pyramid and approach the Veiled statue as well. Upon touching its base, the Darkness-aligned powers of Stasis began manifesting temporarily around her rock much to her surprise. Taking this development of wielding the Darkness under her control, She resolves to accept these newfound powers from the Pyramid as her own.

Trivia

 * At the end of the Scarlet Keep strike, it is possible to see the Pyramid from the gate that the boss comes through. You may have to jump to see it.
 * The reveal of the Pyramid on Luna actually took a lot of the community by surprise and is considered to be the highlight of the campaign for the expansion.
 * The developers intentionally disabled sprint at the point the player first sees the Pyramid, this was done to convey the gravity, danger, and power of the Darkness.
 * When the player encounters the Pyramid of Luna there are two pieces of dialogue that the Ghost can say, what he ends up saying is dependent on whether they saw a projection of the Pyramids in the court of Mara Sov.
 * Ghost Quote 1: "What... is that? I've never seen anything like it."
 * Ghost Quote 2: "That's... one of those Pyramids. It can't be. That should not be here."
 * The Pyramid's outer hull has a similar texture to that of the Traveler.
 * If one looks at the Pyramid from the Enduring Abyss, they can see that the Pyramid is lit up from the outside like its brethren. However, these lights are green, which contrasts from the usual yellow-orange.
 * This may be due to it being inactive for so long and that it's lights have waned in power, or that it has differing lights because its job was different than the rest of the Black Fleet that have been seen.
