Here’s the thing: George R.R. Martin hasn't given us a full, blow-by-blow account of Duncan’s final moments. He died in a massive, tragic fire, but the details are deliciously vague. Think of it like a campfire story where everyone remembers the smoke, but no one can agree on where the sparks first flew. The event is called "The Tragedy at Summerhall", and it’s one of the most haunting blanks in the entire history of the Seven Kingdoms.
What do we actually know? We know it happened in 259 AC, during a grand royal event meant to celebrate the birth of a Targaryen prince. That prince, by the way, was Rhaegar Targaryen—you know, the guy who later kicked off a giant rebellion over a girl named Lyanna Stark? Yeah, that Rhaegar. So, already, Duncan’s death is tied to the biggest domino in the series. Makes you wonder, right?
The "What Happened?" Game
Most fans believe King Aegon V (Egg, Duncan’s old squire buddy) was trying to hatch dragon eggs. Seriously, picture this: an old king, a bit obsessed with the glory of Old Valyria, decides to light a big magical bonfire. But instead of cute, scaly babies popping out, things go horribly, explosively wrong. The entire castle of Summerhall burned to the ground, taking the king and his most loyal knight with it.
Was Duncan trying to protect someone? Was he caught in the inferno while guarding the newborn prince? Or was he simply standing too close to a king who was playing with fire—literally? That’s the cool part: it’s a puzzle box. You get to imagine the scene like a dramatic movie trailer, all smoke and shadow, with Duncan’s massive frame silhouetted against the flames. Chills, right?
