Remnants are caused by the Great Breaks made by the SQ. They are different for each person, and typically involve things that should have happened to someone, but couldn't, due to the Great Breaks. As of Behind Enemy Lines, all three main characters - Dak Smyth, Sera Froste, and Riq Jones - have experienced Remnants of some kind. Sera's Remnants include the feeling of lack of something in a barn in the back of her Uncle Diego's property. Riq just feels some kind of smothering darkness. Dak has Remnants concerning the Cataclysm. Brint and Mari share one, in which they feel they are missing something in a photo.
