Last Wish

Last Wish is a Raid in Forsaken, taking place in the Dreaming City. It is the culmination of the expansion's storyline, and is described as being "like the Vault of Glass and Dreadnaught had a baby." It has the most bosses for a raid yet in Destiny 2. It takes place in an escalating series of encounters throughout the Dreaming City, before culminating within the Keep of Voices, the tower at the head of the Dreaming City.

Bosses

 * Kalli, the Corrupted
 * Shuro Chi, the Corrupted
 * Morgeth, the Spirekeeper
 * Riven, of a Thousand Voices

Kalli, The Corrupted
Guardians will enter a large, empty chamber. The layout is similar to the Blind Well because of the central pit, varying platforms and eight plates around the area. Near the center pit, six icons will appear, with two of each: Heads (two-headed snake), Smile (a snake in a smiley face pattern), Eight (an eight sign), and Infinite (the infinity symbol). One icon will not be shown. There will be a matching plate for each of the icons (I.e. Heads, Eights, and Smiles being shown. Two of each Smile, Head, and Eight plates must be captured. Each plate will have their symbol above or near the side of the plate. Each plate is divided into three sections. Two Taken Blight bombs will be above two of the sections. Stand on top of the empty section of the plate and defend as Taken Thrall and Taken Psions attempt to overwhelm the team. If a plate is held long enough, an Eye of Riven will spawn. Killing the Eye of Riven is not required but helps to greatly guarantee survival in the damage phase.

Also be cautious, as Kalli will be immune and warp to a random plate and attack with blasts similar to a Taken Hobgoblin's defensive bolts. Shortly after each plate has been captured, Kalli will enter the room's center area and attack with bolts and an ability similar to a Psions Psionic Blast. After most of the first segment of her health depletes, she will cast her weapon which will wipe the team. Upon her spell being cast, each Guardian must immediately run into one of the open doors on the side of the well, which are tied to the Eye of Riven enemies. Ensure that you kill an Eye of Riven to guarantee that a door will be open, or you will be wiped.

Trivia

 * Guardian activity during the raid will change the actual Dreaming City destination throughout the first few weeks.
 * The raid is the third to take place in the Ascendant realm, the first being Crota's End, and second being King's Fall.
 * A set of lore tabs in Forsaken offers an explanation as to why Last Wish in particular can be repeated ad infinitum in canon, claiming that Quria, Blade Transform, now attempting to defect from the Taken, trapped the entire area in a timeloop to buy time to undo the corruption of the wish that Riven, the last Ahamkara, granted. However, as these texts belong to an arc involving unreliable narrators, the veracity of this claim cannot be verified, especially since the messenger of said lore series is claimed at different points to be Quria, Eris Morn, the Computer Core Medusa, and Dûl Incaru.
 * The raid is the first to ever feature an Ahamkara as a boss, and also the first to at least partially take place in the Reef.
 * For a short period of time, it was possible to glitch into the environment that the raid existed in and open a raid chest without being in the raid. However, this was disabled by Bungie.
 * The world's first clear of the raid was performed by Clan Redeem in 18 hours and 48 minutes. Their achievement triggered a change to the Dreaming City, causing it to become corrupted by Riven's last wish.
