Egg Targaryen – better known as Aegon V Targaryen or “Egg” from the Dunk & Egg stories and the new A Knight of the Seven Kingdoms show – lives a full life and dies tragically in one of the most important events in Targaryen history: the tragedy at Summerhall.

Who Egg Targaryen actually is

  • Egg is secretly Prince Aegon Targaryen , the fourth son of Prince Maekar Targaryen.
  • In his youth he shaves his head and travels as the squire of Ser Duncan the Tall (“Dunk”), hiding his royal identity.
  • Because so many people stand ahead of him in the line of succession, he later earns the nickname Aegon the Unlikely when he unexpectedly becomes king.

How Egg becomes king

  • Through a series of dynastic twists, deaths, and political crises (including Blackfyre-related turmoil), Egg eventually ends up on the Iron Throne as Aegon V Targaryen, the fifteenth Targaryen king.
  • As king, he tries to improve the lives of common people and pushes reforms that anger many powerful lords, creating tension between the crown and the great houses.

His obsession with dragons

  • Late in his reign, Aegon becomes obsessed with restoring dragons to protect and strengthen House Targaryen’s future.
  • He acquires dragon eggs and convinces himself that if he can hatch them, dragons will return and secure the dynasty.
  • This lines up with earlier prophecies shown or mentioned around Egg in A Knight of the Seven Kingdoms , which hint that he will become king and die in fire.

What happens to Egg in the end (Summerhall)

  • Near the end of his life, Aegon takes the dragon eggs to Summerhall , a Targaryen royal residence in the Stormlands.
  • He attempts a risky dragon‑hatching ritual that apparently involves wildfire and other dangerous methods.
  • The attempt goes horribly wrong: a massive fire engulfs Summerhall , now remembered as the tragedy at Summerhall.
  • Aegon (“Egg”) dies in that fire , along with:
    • His eldest son, Prince Duncan Targaryen
    • His old friend and protector Ser Duncan the Tall (Dunk)

Most sources agree on these broad facts but keep many details mysterious, especially exactly how the ritual was performed and who, if anyone, may have survived beyond the well‑known names.

What it means for the Targaryen line

  • Even though Egg dies at Summerhall, some of his descendants survive, including his grandchildren Rhaella and Aerys , with Aerys later becoming the “Mad King.”
  • Lore discussions and fan analyses often describe Summerhall as a turning point, marking the start of the final decline of the Targaryen dynasty that eventually leads to the events of Game of Thrones.
