A Feast for Crows
Behind the Scenes
The mention of Alester blowing a warhorn with his last breath in the Prince's Pass may be a reference to The Song of Roland, in which Roland dies shortly after sounding a warhorn to call for aid from Charlemagne's army, after being ambushed in the Roncevaux Pass.
