Three-Eyed Raven

The three-eyed crow is a figure that appears in Bran Stark's dreams, following his fall and injury. In Bran's dreams, the crow appears to be trying to lead him to a location of importance in Winterfell, but it is unclear exactly what.

In the books
In the Song of Ice and Fire novels, the crow is more active in Bran's dreams, helping him wake from his crow and inspires him to name his direwolf Summer. Unlike in the TV series, the crow can talk and tells Bran it can teach him how to fly. It also calls him 'The Winged Wolf'.
