These letters are found on a dead messenger in the Wounded Coast during Dragon Age II, along with Silverite Threaded Gloves and a vial of Avernus' Experimental Research, which grants an ability, and three attribute points. It also triggers the quest Dark Epiphany. If Soldier's Peak was not completed, or if Avernus was killed, the messenger's corpse will not appear.
Codex Text
Take the first boat from Amaranthine to Kirkwall, then proceed with all haste to Weisshaupt Fortress. If the roads prove too perilous or blocked, ourr agent in Kirkwall can assist. Find the dead drop located in an alleyway near the Lowtown foundries during daylight hours. Protect the letters at all costs.
If Avernus was told to continue with his research ethically -
The limitations put upon my research have greatly hampered progress. With just a few subjects, I could test certain critical hypotheses. However, the information sent about the Architect has proven invaluble to my efforts, and I am pleased to report limited success. As the Architect surmised, considerable untapped power exists within Grey Warden blood. When properly prepared, its effects can be remarkable.
But my research has also revealed some alarming implications, which I've attached in the old Acanthan cipher. I urge you to send this to the First Warden at once.
I will conduct further tests as long as I'm able. My documentation is very thorough - if time finally claims me, others may follow in my footsteps.
Avernus
Notes
- The words of Avernus' letter to the Warden-Commander will vary slightly depending on choices made in Dragon Age: Origins - Warden's Keep, as will the effects of the potion found alongside the documents.
