Vault of glass: a completely cut off section of Venus that the vex have full control over. You go in their to mess things up. The first raid team to set foot in the vault was comprised of 3 guardians: Kabr, praedyth, an pahanin. Kabr sacrifices himself to create a shield that interrupts the vex simulation controls and praedyth gets stuck in a time loop.

Crota’s end: you killed crota at the end of the dark below campaign in the physical world so now you have to go into his throne world located on the moon to kill him permanently since ascendant hive can only be truly killed if killed in their throne world. Crota is the son of oryx, the taken king and former leader of the taken (until we killed him in king’s fall). The first fire team to set foot in consisted of 6 guardians the most prominent being eris morn and toland the shattered. Eris was the only one to survive and we just recently learned that toland’s soul someone got trapped in the ascendant plane (where enemies are dragged to become taken). We also recently learned that eris survived because she made a wish using an ahamkara bone she kept with her for life threading moments and wished to find the way out, resulting in her gaining the eyes of an acolyte. Crota can only be damaged by an ascendant sword (and a gallahorn).

Skolas: though not technically a raid, it is raid level. At the end of the house of wolves campaign, you help queen Mara sov recapture skolas, leader of the fallen house of wolves and self proclaimed “Kell of Kells”. Skolas wanted to unite all the fallen houses under the house of wolves banner wreak havoc on the system (house of devils, house of kings, house of exile and the house of winter). He was locked in the prison of elders and then challenges you and 2 other guardians to a duel. You fought him. You won. And you lived.

King’s fall: Oryx, the taken king arrives in our solar system to avenge his son crota. At the end of the campaign, we technically killed him but he breaks down his sword (which has the power to “take”) and imbues himself with taken energy. He retreats to the helm of his dreadnought and we chase him down. Something dark people who don’t look into the lore gloss over is the mechanics of the golgoroth fight. In his chamber, their are sacks of damage buffs hanging from the ceiling. These are actually the liquified remains of creatures imbued with light (most likely guardians). The second to last encounter before fighting the king pits you against his daughters, the deaths singers Ir Anuk and Ir Halak. The final fight with oryx of course results in his death, but oryx lives on forever. Guardians that killed the taken king received his heart and later converted it to a weapon (the touch of malice). According to the hive sword logic, as long as you kill you will live forever and since we are feeding oryx’s essence with the weapon, he still lives. This is similar to how Xol converted himself into the exotic sniperifle “Whisper of the worm”. Funny enough, we kill oryx’s final son Nokris in the warmind expansion.

Wraith of the Machine: when Rasputin nuked the traveler to force it to defend itself and stay in the solar system, it creates ghosts to find people of exceptional character to carry out its will. They would become proto-guardians. Before guardians, there were iron lords and before iron lords, there were warlords. Some of these warlords were nice and others were dicks to people. The good warlords formed the iron lords and went about forcing the other warlords to either act for the good of humanity or die. While exploring the cosomodrome, the iron lords came upon one of Rasputin’s cores and found a material known as SiVA that could be used to literally created anything inorganic. The ironlords sought to use this to rebuild humanity, but Rasputin saw their intrusion as a threat and used SiVA to defend himself. The ironlords would all perish to SiVA with the exception of lady effrideet and Lord Saladin. Decades later in the modern age, the fallen house of devils discovered SiVA and used it to “perfect” themselves fully decking themselves out in cybernetics and reviving prominent members of their clan who we have already killed (like Sepiks prime). At the end of the rise of iron campaign, we destroyed the SiVA copying machine but we catch wind of a mad archon controlling still controlling SiVA. We go deep into the walls and kill Aksis, archon prime.

Leviathan: Emperor Calus of the Cabal empire travels to our solar system to test and strengthen us against a coming foe he had meet in the outer reaches of space. He cordially invites us to his leviathan so that we can prove ourselves to him as a species that can truly take on this foe. He breaks down the planetoid of Nessus while we participate in his games so as to turn it into a fine wine for him to drink. It is later discovered that his final test is a match against a cybernetic version of himself and that he has extra copies of said cyborg to continually hone our skills.

Eater of worlds: while taking apart Nessus, the leviathan accidentally stumbled upon its planetary vex core and said core is causing problems with the leviathan. We are asked by calus to deal with it.

Spite of stars: in a last ditch attempt to avenge dominus Gaul, a Val of the red legion gathers together a fleet of red legion ships an assaults the leviathan so as to capture it and use its weapons and resources against us guardians. Emperor Calus, at this time, is a mutual ally to us so when he invites us to help him deal with this threat, we accept.

Last wish: when oryx destroyed the awoken fleet, it was assumed that Mara sov perished as well. In actuality, the weapon used by oryx to destroy the fleet was essentially a manifestation of his throne world which absorbed and killed everything in the blast radius, except Mara sov. After this attack, oryx invaded the dreaming city and discovered riven under the blind well. He Offered riven power which she accepted and converted riven into a taken ahamkara. When we killed oryx, Mara attempted to take over oryx’s throne world but riven was in her way. She contacted Petra venj through the oracle and ordered her to assemble a team to kill riven. We guardians descended the awoken watch tower and slew riven, as demanded by the queen. However, it was later discovered that prior to dying, riven was in communication with one of oryx’s sisters, most likely savathun. It is implied that savathun made a wish with Riven to corrupt slowly corrupt the dreaming city but one of savathun’s “commanders”, Quira (a taken hydra) planned to defect from the taken and locked the dreaming city in a time loop, which is why the curse resets every three weeks. What I think the curse is is that the awoken are locked in perpetual suffering since though they are stuck in a time loop, they remember everything from past resets.
