Meiyerditch citizen is a vague term given to NPC residents of Meiyerditch. They have white skin and hair and are seen throughout Meiyerditch. Meiyerditch citizens are forced to give blood tithes or do menial work for the vampyres who dominate the Sanguinesti region of southeastern Morytania.
If spoken to, Meiyerditch citizens can help players by sharing what they know of The Myreque, explaining the nature of the ghetto city, or sharing their knowledge about what sector of the city the player is currently in.
You need to talk to a Citizen during Darkness of Hallowvale to find your way to the Myreque headquarters in Meiyerditch. During the quest you need to whisper to them about the Myreque and they will point you to Old Man Ral.
