To find and join the Thieves Guild in The Elder Scrolls IV: Oblivion, you need to go to the Waterfront District of the Imperial City, specifically to the Garden of Dareloth, located behind the Abandoned Shack near the pirate ship. You must be there at midnight to meet Armand Christophe, a representative of the Thieves Guild, who will initiate you with a task to prove yourself
. There are several ways to trigger the quest to find the Thieves Guild:
- Get caught committing a crime and sent to jail. After release, you will be approached with an invitation to meet at the Garden of Dareloth
- Investigate wanted posters of the Gray Fox around the Imperial City, then talk to beggars in the Waterfront District who will eventually tell you about the guild and direct you to the Garden of Dareloth
- Simply go to the Garden of Dareloth at midnight without prior knowledge, and you will find the meeting to join the guild already happening
Once at the meeting, Armand will give you your first task: to steal a journal from Aius Electus in the Temple District without killing him. Completing this task officially inducts you into the Thieves Guild
. In summary, the key location to find the Thieves Guild is the Garden of Dareloth in the Imperial City Waterfront District at midnight, where you meet Armand Christophe to start your initiation
