House of Dusk
The House of Dusk is a Fallen House, distinguishable by their dark purple cloaks and armor. They recently emerged following the advent of the Red War and were founded by the former Awoken Prince Uldren Sov under orders of Craask, Kell of Kings. They are engaged in conflicts with every other faction in the system.
Some time after the Reef's disastrous attack on the Dreadnaught, the surviving Prince Uldren Sov allowed himself to be captured by the House of Kings in order to gain an audience with their Kell, Craask. Craask reluctantly bent the knee to Uldren, and beseeched him to carry the message to every other Fallen House to abandon their old loyalties, end their rivalries and join together for the sake of survival.
Following the Devil Splicers defeat at the peak of the SIVA Crisis, the Fallen collectively retreated from all of their hardcore strongholds, leaving behind their banners and armor in ceremonial piles and burnt ash. 
Nearly a year after the SIVA Crisis, around the time of the Red War, the House of Dusk suddenly emerged, with no sign of the other Fallen Houses being present outside of ruins. The House of Dusk entered a massive guerrilla war with Red Legion forces across the Solar System as well as battling the Hive and Vex.
The House of Dusk are first encountered in the mission Spark. A former Wolf noble, Skriviks, who disappeared after the Wolf Rebellion returned under the banner of Dusk. Accompanied by her lieutenants Tikkis and Maksor, she and her crew launched a counterattack to reclaim the Shard of the Traveler, but met their end when the Guardians regained their powers.
Later when the Guardians returned to attain new subclasses, they met resistance from Poknis, Order Captain, a Prime Servitor named Brandaks Prime and a heavy shank. The Fallen were trying to harness the corrupted Light of the Traveler's Shard, but ultimately failed.
In the European Dead Zone, Raksil, Archon Priest and Serkuleks, the Fount were responsible for producing and distributing an enhanced variety of ether by using modified Cabal technology. This would strengthen the nearby Fallen into an class of Empyrean capable of eliminating the Cabal.
During the Larceny mission, the High Servitor Teleks-5 led an offensive against the Cabal alongside a crew of Fallen to scavenge supplies. Later in the Arms Dealer strike, the House of Dusk would infiltrate Firebase Hades again and enter a massive battle against the forces of Bracus Zahn, a weapons supplier who for the Red Legion. They were however pushed back by a Fireteam when the Vanguard enlisted them to eliminate Zahn. The increased campaigns against the Cabal highlight a greater show of strength especially when former Houses would refrain from such tactics.
When Commander Zavala fled to Titan to establish a secret base against the Red Legion, the House of Dusk saw an opportunity to follow him there. The Fallen quickly got to work after finding long abandoned Golden Age cities such as the New Pacific Arcology ripe for plunder and intercepted many unmanned shipments sent to Earth by Sloane.
As they encroached into Hive territory, the two races began a bitter feud. In the Savathûn Song strike, the Fallen fought for dominance against the Guardians as the two sought to investigate the Hive territory past the Solarium.
Later a group of Fallen led by Mithrax, the Forsaken compete against the Guardians to gain access to an ancient methane reactor with the motivation of boosting Ether production for Servitors by doubling or tripling the output.
Mithrax would always be one step ahead of the Guardians by constructing various barriers along the way and enlisting the High Servitor Selkis, the Obstructor to further halt the Guardians progress. Fallen Walkers would be deployed to fend off Hive Orges and Knights swarming the complex.
Finally Mithrax is seen duelling against Golthor, the Subtle in which Guardians are given a choice in who to kill. By killing the Hive Knight and sparing Mithrax will trigger an ending in which he'll thank the Guardians with an Eliksni display of respect to Zavala’s surprise. He disappears and grants the player access to the reactor, putting question to Fallen and Human alliance.
After following Cayde-6 to Nessus, the House of Dusk quickly establish themselves by setting up Fallen comms with Titan and EDZ, forming a triumvirate communication network using modified House of Kings encryptions.
In the mission Six, the Dusk launch an large scale attack against the Vex near the remains of the Exodus Black. The Vex displeased with the Fallen moving into their territory go into a muderous rampage and defend themselves with Acanthos, Gate Lord. The Dusk counter with Fallen Walkers and push pass the Vex.
Jaliks, Fallen Captain the commander leading the charge arrives and stations his Ketch above the Exdous Black. His crew attempt to crack Failsafe's defensive shields and deploy Servitors to hack the network, only to short circuit. They also set up terminals for remote access into Exodus Black's security system. Jaliks would ultimately die at the hands of the Guardian.
In Exodus Siege, the Dusk continue their pursuit to destroy Failsafe’s mainframe so they can scrap her for parts. Elyksul, Assault Leader leads the second assault and corrects past mistakes by deploying special Assault unit with cloaking and send signals behind a massive barrier powered by Vex tech to avoid detection. The Guardian intervenes by annihilating the assault and trace’s Elyksul back to their hidden cavern. After fighting through numerous Barrier Servitors, they kill the Captain and end their siege.
In Exodus Crash, the Dusk attempt a third raid on the Exodus Black, this time on the secondary hull where Failsafe is blind. Thaviks, the Depraved lead this raid, holding himself up inside the hull and deploying even more forces, which included Walkers and Heavy Shanks outside the area. However, a Fireteam lead by the Guardian was able to break through the defensive line and kill Thaviks, discouraging anymore Dusk Fallen from raiding the Exodus.
Though the Fallen would try to scrap Failsafe at various points, she however would be sympathetic towards them when the Vex start imprisoning the Fallen. Failsafe enlists the Guardians help in the adventure Release to fight through the Vex network and free the Fallen. Later it is discovered that Vex promised to release the Fallen only if they fight each other to the death, but the Fallen held together by genuine loyalty did not attack one another, signifying a end of old House rivalries
With the release of former intimates and the demise of the House of Wolves, the House of Dusk saw a surge of membership which included the Silent Fang, Queenbreakers, Pallas Seigebreakers and those afilliated with Beltrik and Irxis.
Despite having these new recruits, the House of Dusk continues to splinter and suffer, as agents of the Last City have observed that many of its members deserted to either join the Kell's Scourge, led by Siviks, Lost to None, or strike out on their own. Following Sivik's mounting failures and eventual death, the House of Dusk continues to fracture and radicalize, the result of a lack of leadership.
A year after the events of Forsaken, the house is now more fractured and divided than before. The return of the House of Devils, the emergence of the House of Light and Variks, The Loyals's House of Judgment have only further drained the ranks of what was once considered a unified Fallen House. Despite this, however, the Fallen have seemingly made one last haven for themselves on the Moon. Exploiting a crashed Ketch, they now hold a lot of the old territory that they once did. Even despite this, the legacy of the House of Dusk seems to be drenched in failure, at the start of the Red War, they were the largest House ever to threaten the System. But their constant defeats at the hands of the Guardians and with no Kell in the absence of an Elder Cipher, they have no legitimate leadership.
If there is one obstacle to this, it is that once the House of Dusk finally breaks, three new Houses will rise from its ashes. The return of the vicious House of Devils and the rise of an ally in the form of the House of light, along with the mystery of Variks the Loyal's rising House of Judgment will illustrate how the Eliksni as a species taking up sides.
Season of Dawn
Even though the house itself does not appear in present day, it is revealed that the House of Dusk adopted their purple banners from the House of Rain that attacked a settlement of Mercury when it was still a garden world.
Primarily distinguishable by their dark purple cloaks and new weapons, their eyes glow an intense turquoise, much brighter than the pale blue seen in Fallen from Destiny 1, and wear very little armour, instead choosing to rely on their natural exoskeletons for protection. What armor remains is heavily weathered and worn down.
The House can be found on Earth, Titan, Nessus, and Luna, warring with every other alien faction in the system. Within the House of Dusk, the Fallen no longer worship Servitors and machines as they used to, having devoted their energy towards simple survival. With their emergence, they are believed to be the most powerful active Fallen faction in the Solar System.
Evidence strongly imply that the House of Dusk is an amalgamation of the remnants of other Fallen Houses. Dusk structure bear a level of complexity similar to the House of Wolves. There are multiple specialized forces that are given their own set of tasks. Pike gangs are sent to patrol Fallen territory and harass intruders. Signal crews led by recon specialists and stealth troops hack into and jam communication devices used by enemy forces to prevent them from strategizing. Glimmer extraction crews use Glimmer Drills to acquire wealth and resources. All of these divisions are given their leaders from the ranks of their nobility. The whereabouts of their Kell and Barons is unknown. Therefore, its possible that while united for the sake of survival, they operate independently from each other.
The House of Dusk is actively calling other Fallen to join with it. Fallen banners displayed in Trostland bore a crude version of the House of Judgment's sigil, but the banners were seemingly used as warnings rather than to mark territory ownership. Some Fallen tech also found in the area once belonged to the House of Winter and had been transported from Venus. While a communications device in Siren's Watch was discovered to be using variants of encryption protocols derived from the House of Kings. A former noble of the House of Wolves was found to have joined the ranks of the House of Dusk. Lastly, the House produces Heavy Shanks based on the House of Devils' S.A.B.E.R.-2 prototype. Ghost notes that where Skolas failed in uniting the Houses, sheer desperation (due to the massive losses faced in the Taken War and SIVA Crisis) succeeded in burying old grudges.
Another unusual characteristic is that it utilizes Servitors from multiple lines (Brandaks, Drensik, Kendriks, Kiriks, Merix, Nariks, Selkis, Serkuleks, and Teleks), a practice previously only seen with the House of Wolves, which used two lines (Kaliks and Orbiks). Furthermore, it possesses multiple Prime Servitors where no Fallen House had been known to follow more than a single Prime Servitor at once, and which were almost never deployed offensively except where the Fallen believed that they had an overwhelming advantage or when their lair was invaded. The House of Dusk went against traditions by regularly sending Prime Ether Servitors to directly distribute ether to crews in combat zones on various worlds, and deploying other Primes like Brandaks Prime and Serkuleks, the Fount as reinforcements against Guardian incursions.
In addition to their scavenging, the House of Dusk also appears to be focusing on Ether production and experimentation. In the European Dead Zone, Raksil, Archon Priest and Serkuleks, the Fount were responsible for producing and distributing an enhanced variety of ether from Cabal technology that strengthened the Fallen. In the Arcadian Valley, Ghost scanned a tank with ether that had been diluted through unknown means, which he speculated meant that the Fallen on Nessus were experiencing a dire ether shortage. Equally intriguing is that many of the House of Dusk's Captains throughout the system are comparable to Kells in size, a level of growth which requires a large amount of ether to achieve.
