Estrith is a Fremennik woman who wanders around the outer-castle of Daemonheim as a sentry for the Fremennik.

She seems extremely bored and makes sarcastic comments frequently, such as:

• "Yet another round with nothing interesting happening."
• "Soon we'll be home eating red meat and combing innards from our hair." (To Wiglaf, the Fremennik cook to the east of Thok.)
• "Time to do my rounds, I suppose."
• "If that smuggler is sneaking about again, I'll have his head on a rusty pike." (When she is near the banker.)
• "Hey you! I've got my eyes on you. You better not try any funny business around here."
• "Oh look! Some rocks! Oh, and some more rocks! It can't get more exciting than this."
• "I've got the eyes of a hawk, the ears of a wolf, the speed of a kyatt and an awful day job."
• "If I never see another floating eyeball in a hundred years, it'll be too soon." (South of Thok)
