Before Guinevere Pendragon became Queen, she lived in a small house, which she used to share with her father, Tom. It's a simple house. It has a bed, a table, and a few shelves and drawers. Gwen and Elyan were born and raised in this house. During the several years, many significant occurrences have happened here. Gwen eventually left this house and resided in the palace after being crowned Queen of Camelot. In A Lesson In Vengeance, Tyr Seward's house looks a lot like Gwen's old house which he shared with his mother until his death later in the episode.
