The Altar of Mythal is in a large clearing within the Arbor Wilds. Lead your party to the objective marker to locate the altar on the south side of the clearing. Interact with the altar to summon Mythal. Soon after the summoning, a mysterious woman comes walking across the clearing—Morrigan clearly recognizes her as Flemeth. Morrigan is confused, yet the voices from the well say Flemeth speaks the truth. Flemeth warns that the altar’s guardian will come soon. If you defeat it, the guardian will serve you in the battle against Corypheus. Flemeth then turns around and walks off into the clearing, leaving you to face the guardian of Mythal.
The dragon battle is necessary only if the Inquisitor drank from the Well of Sorrows. If Morrigan drank from the well, she becomes the dragon—see the table to clarify what happens based on your custom world state. Return to Skyhold following the conversation with Flemeth.

Guardian of Mythal
Immediately following the conversation with Flemeth, prepare yourself for a dragon battle. You must tame the ancient dragon by defeating it in battle in order to gain its allegiance. This fire-breathing dragon is vulnerable to cold-based attacks, so waste no time hitting it with Winter-based abilities like Winter’s Grasp, Ice Mine, and Blizzard or Ice Storm. Target the dragon’s front two legs first to hinder its mobility. Once the front two legs have been disabled, target the dragon’s head.
Area-of-effect attacks are very effective against this dragon, including grenades like a jar of bees. Before initiating an AoE attack, wait until the dragon hops to a new location. This will ensure the dragon takes the brunt of your AoE attack. Also, try to position the AoE attack directly under the dragon’s head and front legs. This way the attack damages all three targets. Wait until the dragon’s guard is diminished, then unleash Mark of the Rift to dish out some heavy damage—this is a good way to finish the battle.
It takes time and persistence, but eventually the dragon’s health will be depleted. However, it’s not dead. Instead, the dragon yields to the Inquisitor’s commands before flying away. The Inquisitor reports that the dragon will return when summoned. Now, exit the clearing to the west to return to Skyhold.
