How & Why Egg Burned Down Summerhall - A Song of Ice and Fire - Dunk and Egg - Game of Thrones

What was "King Egg" (a.k.a. Aegon V) trying to do at Summerhall, and why did it go so horribly wrong? Those are the questions I'll answer, covering both the well-established Summerhall theories as well as some new ideas I am bringing to the table. Explosive dragon's eggs, visions of the Prince That Was Promised, kingsblood, wildfire, and potential maester conspiracy, plus a new find for the "Dunk held the sand-door at Summerhall" theory, it's all here.
