In the books
In the Song of Ice and Fire novels, Ser Jaremy is an officer in the rangers of the Night's Watch. Ser Jaremy attends the officers meeting with Tyrion Lannister and recalls being sent to the Wall by Tywin Lannister after fighting for House Targaryen against the House Lannister in the Sack of King's Landing during Robert's Rebellion.
