After obtaining the Ashen Mist Heart from the Ancient Dragon in the Dragon Shrine, go back to the Duke's Dear Freja boss room and you will find a crystal lying right below the dragon hanging from the roof. Interacting with it will cause you to access a dragon memory.
The player will find themselves in a grey, foggy place. Explore a bit and you will find the corpse of what seems to be an Everlasting Dragon, get close to it and you will obtain the Ancient Dragon Soul.
- The dragon memory seems to be located after the War with the Dragons during the Age of Ancients from Dark Souls.
- This is one of the few areas of the game that has its own atmospheric soundtrack.
- Dropping anything in Majula will cause it to appear in the sky of this area.
