Ancient Dragon Soul
Ancient Dragon Soul is a consumable item in Dark Souls 2.
- In order to get this soul, you need the Ashen Mist Heart, which you will get near the end of the game. After that, go to the boss room of The Duke's Dear Freja and examine the statue below the Dragon head. You will be transported to Memories of a Dragon with a giant Dragon Corpse. Examine the head of the Dragon to get the Soul. NOTE: The Ancient Dragon only drops a Giant Soul.
- It's likely that this soul was supposed to be dropped by the Ancient Dragon as it describes the NPC who "stands magnificently, deep within the shrine." It may have been moved into the memory due to the difficulty of the boss battle or some other development reason. Alternatively, there are many theories supported by in-game evidence that the Ancient Dragon NPC is an imposter or a fake, implying that the NPC does not possess a legitimate Ancient Dragon Soul, which is why it is obtained elsewhere.
- This soul will NOT be respawned by using an ascetic on the bonfire.
This dragon bears the most resemblance to the dragons in the opening cutscene of Dark Souls 1, which combined with the destroyed archtrees and the overall grey setting, suggests that it was killed in battle by the army of Gwyn, Lord of Sunlight in the "Age of Ancients." It is unlikely to be Seath or the Everlasting Dragon from Dark Souls 1, due to the difference in appearance between them. It is highly likely that the Ancient Dragon was formed by Aldia from the likeness of this dragon, and that the two would have looked almost exactly the same, with similar powers and strength.
However, the Duke's Dear Freja does drop the soul of Seath, suggesting that the Duke himself was somehow influenced by Seath's soul which was channeled by the body of this dead dragon underneath Brightstone Cove Tseldora. There is a possibility that this dragon could have been one of those killed by Seath himself. Ultimately he seems to have used this power to create Freja.
