Riven's Heart

Riven's Heart is the object at the centre of the Queenswalk, the final encounter of the Last Wish raid. Riven's heart sits in her throat. After her death, a player runs down her throat to shoot it, and after the final phase players enter her mouth and shoot the heart to start the Queenswalk.

One player carries the heart and receives the "Fate's Chosen" debuff, with a countdown of about 15 seconds. If it reaches zero, the carrier is pulled into the heart and someone else must pick it up. Taken Strength orbs along the route reset the timer, but the player who grabs one is teleported inside the heart to collect motes for the next carrier. Fireteam members must stay in an aura to avoid the Creeping Darkness debuff. The goal is to return the heart to the pool at the entrance of the gravity lift.

A popular shortcut uses the Titan Behemoth with the Diamond Lance aspect. Sources vary in age and Bungie has changed raid mechanics over time, so check a recent guide.
