The Well of Sorrows whispered of a power in the Arbor Wilds strong enough to end Corypheus.
Your party emerges from Morrigan’s eluvian back in Skyhold. Back in the war room, Cullen reports that Corypheus retreated from the Temple of Mythal when you escaped through the eluvian. The council is uncertain what Corypheus’s next move will be. If the Inquisitor drank from the Well of Sorrows, vague whispers can be heard—Morrigan is annoyed by the Inquisitor’s inability to interpret these vocalizations from the well. Nevertheless, the Inquisitor is able to glean some helpful information regarding Corypheus’s weakness—his dragon. If the dragon is killed, Corypheus’s ability to leap into other bodies will be temporarily disrupted, leaving him vulnerable. Guided by whispers from the well, the Inquisitor identifies a remote location on the war table—this is where the Inquisition must travel next. Upon exiting the war room, access the world map and travel to the Altar of Mythal. When selecting party members, consider bringing along a couple of mages with ice staves and Winter abilities.
