The simple answer is: Duncan the Tall died in a wildfire-like inferno at Summerhall, probably while trying to protect the royal family or helping his king with a crazy dragon-egg experiment. But the real answer is more interesting. He died in a mystery that fans still debate over coffee. He died in a way that made him a martyr and a ghost who haunts the story’s edges.
Isn’t that the coolest kind of death? Not a simple "stabbed by a bad guy," but a glorious, ambiguous, world-shaking disaster. It leaves you asking "What if?" and "How?" For a knight who stood seven feet tall, only a death that burned bright enough to light up the history books makes sense. And honestly, isn’t that how every hero should go out? A little smoke, a lot of questions, and a legacy that never quite fades away.
