Upon the Waking Sea is a war table mission in Dragon Age: Inquisition. Must have completed the previous operation, "The Secrets of Andraste" and have an Inquisition level of 4 or more for this to appear. Will not be available upon moving to Skyhold.
The Alamarri runes found in the mountain passages outside Haven have finally given up more of their secrets, pointing to one of the larger islands off the northern coast of Ferelden. The island is quite large and covered in dense wilderness, so searching it will be an involved process. According to the runes, however, there should be some connection to the original disciples of Andraste and the “Guardian” of the Sacred Ashes.
We found what we were looking for: an ancient vault all but buried in the thick vegetation at the heart of the island, no doubt untouched for over a thousand years. The effort to open the vault without setting off traps was considerable, and what we found within was… interesting. According to an agent named Rion, this was the retreat of one of the last of Andraste’s disciples, a guardian who fled some manner of attack on the site of the Sacred Ashes. He expect reinforcement by other disciples who never arrived.
Whatever texts the man thought to preserve have mostly crumbled, but we recovered a number of other artifacts from the site. It is a significant find that will undoubtedly prove of great interest to Chantry scholars, even if it will take them years to sort through all the debris.
