Follow Spy is a quest given by a lord of a friendly faction. You must have at least one hero that is level 15+ in your party. You will be asked to follow a spy who is trying to meet with his accomplices and, preferably, capture them both. Capturing only one of them will complete the mission, but anger the person who gave you the quest. Capturing the spy only will negate the relation you earn for accepting the quest, while taking the facilitator, but not the spy, will still net a small reputation increase. It takes 50 days to appear again.
