Read the Tainted Letter and speak to Drusilla La Salle next to Northshire Abbey.
- Tainted Letter (Provided)
I was asked to bring this to your attention as soon as you returned from dealing with the Blackrock spies, <name>. It appears to be a letter sealed with the insignia of Drusilla, one of our local trainers. I wouldn't hesitate to read it before you go about any other business here in the Abbey.
