Destiny 2’s upcoming DLC expansion, Curse of Osiris, will feature a new type of Raid experience called a Raid Lair.
As detailed during Bungie’s Twitch stream (via Game Informer), a six-player Raid Lair is shorter but "no less challenging" than your standard Raid encounter. Curse of Osiris’ Raid Lair is titled Leviathan, Eater of Worlds. Like the existing Leviathan Raid, Eater of Worlds is also set on Calus’ planet-eating ship; however, the action takes place in the lower areas of the ship rather than all the way at the top.
