Methredhel is a bosmer archer and pickpocket of the Thieves Guild. She is one of its newest members and one of the thieves you contend with for entry. Like most thieves she lives a nocturnal lifstyle, sleeping all day and active all night.
She lives in a house on the Waterfront with Adanrel and Carwen but unlike them she makes something of herself in the guild eventually becoming a messenger for the Gray Fox himself. Methredhel is sometimes a contact for the player and frequently comes up with good plans to help fellow thieves and the Gray Fox.
