Letter: The Underground Railroad

The Underground Railroad is received at the start of Act 2 if you helped Terrie escape during Act of Mercy.

Letter
Many people in the city owe you their lives, and I am one of them. When my friends and I were cornered by templars, you helped us escape. Over the years, most Starkhaven apostates have been captured. But thanks to the help of many people, I have remained free. You've done so much for the apostates—if you are moved to do more, contact Mistress Selby near the Docks. She knows of many ways you could save more lives.

Forever in your debt, Terrie of Starkhaven
