A Brewing Conspiracy is a side quest in Dragon Age: Origins - Awakening.
Background
Find Out more about the conspiracy
- The quest can also be started by speaking to Anders during the ceremony. He'll reveal that he overheard some things from unidentified nobles that indicated a conspiracy.
- Ser Tamra thinks there is a conspiracy afoot she has gone to collect more evidence.
- Ser Tamra intercepted some missives from nobles that look like they are planing to kill the warden-commander for what the commander did to Rendon Howe.
Walkthrough
Start the quest by talking with Ser Tamra during the quest Oaths of Fealty in Vigil's Keep - Throne Room
Return to Seneschal Varel and discuss Ser Tamra's revelations. Senseshal Varel informs the Warden that the right of high Justice is theirs and treachery is a capital offense. Senseshal Varel presents the Warden with 3 options:
- 1st option find an infamous character called the Dark Wolf (If you did the side quests from Origins called Crime Wave, you will remember that Slim Couldry told you that the nobles were calling you the Dark Wolf). Leads to Dark Wolf option below.
- 2nd option let the conspirators set a trap for the Warden is chosen, Ser Tamra will eventually return to the Warden (the Seneshal does not recommend this). Leads to the side-quest "And You, Esmerelle?"
- 3rd Option You can Invite each Nobel to stay for a week and making them your hostage. and if anybody moves against you you have them executed.
- 4th option is having some soldiers spy on the nobility, but the Seneshal does not believe that the soldiers will be successful (this option does not really lead anywhere).
Dark Wolf Option
After entering the city, a cut scene is triggered and a city guard explains to the Warden that she was paid to deliver a letter from a knight called Ser Wolf of Rivian. If the Warden asks about the knight, the city guard explains that he had on a helm and has no other information, but that he looked suspicious.
The suspicious guard can be found in front of the second gate in Amaranthine at the north end of the city. (During the conversation, the Warden can reveal that he/she is the Dark Wolf, if the Crime Wave quest was completed in Origins). The Dark Wolf requires a payment of 50 
in order to reveal the loaction of the conspirators, but that it will take some time to find the information. At this point enter any building and then return to the supicious guard. He tells the Warden that it was not easy, but he knows where they meet. A new location appears on the world map named Old Stark's Farm. Travel there and kill the conspirators.
