Destiny 2: Forsaken's first Raid is hours away, and we're getting a small peek at what it'll entail and when it will drop. Last Wish will take players and five other guardians into the heart of the Dreaming City, Forsaken's new area, and it will go live on Friday, September 14 at 10AM PT / 1PM ET / 6PM BST on PS4, Xbox One, and PC. [Update: The Last Wish Raid is now live on all platforms.]

"Assemble a team…Send them into the heart of the City. Kill that creature, and extract its heart," says the Queen, Mara Sov, in the trailer above. We don't much else about what exactly players will be doing, but it seems the "creature" could be Riven, which was teased at the end of the campaign. The promise is "the riches of the Dreaming City await those who are victorious," so you could be in for some pretty good loot if you successfully complete it. "I've waited so long to fulfil one last wish," Mara Sov finishes.
