The Bloodline Of Fire: 7 Shocking Secrets Of The Updated House Of The Dragon Family Tree (Season 2)

The Targaryen family tree is not merely a chart of lineage; it is a map of the impending civil war known as the Dance of the Dragons, and understanding its latest branches is crucial for navigating the brutal events of *House of the Dragon* Season 2, which concluded in August 2024. This guide cuts through the centuries of incestuous marriages and disputed parentage to highlight the key players, their blood ties, and the claims that fuel the conflict between the Blacks and the Greens. The battle for the Iron Throne is a family affair, and the complex web of siblings, half-siblings, and cousins makes every death a devastating personal blow to both sides.

The core of the conflict traces back to King Viserys I Targaryen and his two marriages—first to Aemma Arryn, producing Princess Rhaenyra, and second to Alicent Hightower, producing three legitimate children, including the usurper, King Aegon II. With the war now fully ignited, the focus shifts to the children and grandchildren of Viserys, as they are the true dragonriders and heirs whose fates will determine the future of Westeros. The latest updates from the series clarify the precarious positions of figures like Daemon Targaryen, Corlys Velaryon, and the children of Rhaenyra, making the family tree a vital resource for any fan.

The Grand Lineage: From Jaehaerys I to King Viserys I

To grasp the current crisis, one must look back to the man who secured the Targaryen dynasty’s golden age: Jaehaerys I, "The Conciliator." His reign of nearly 55 years set the stage for the succession crisis that would later tear his house apart. His decision to pass over his older daughter, Rhaenys, in favor of his grandson, Viserys I, established the precedent that women could not inherit the Iron Throne, a ruling Rhaenyra now seeks to overturn.

• Jaehaerys I Targaryen: The fourth Targaryen king, known as the Old King. He married his sister, Alysanne.
• Baelon Targaryen: Jaehaerys’s son, who was the father of Viserys I and Daemon Targaryen.
• Rhaenys Targaryen: Known as "The Queen Who Never Was," she was Jaehaerys’s granddaughter (through his son Aemon) and was passed over for the throne. She married Lord Corlys Velaryon, creating a powerful alliance between House Targaryen and House Velaryon.
• King Viserys I Targaryen: The fifth Targaryen king, whose indecision and two marriages are the direct cause of the Dance of the Dragons.

This early lineage establishes two critical entities: the royal line through Viserys I and the powerful, dragon-riding Velaryon line through Rhaenys and Corlys. The Velaryons, who control the seas, become the primary allies of Team Black.

The Core Conflict: Team Black vs. Team Green (The Children of Viserys)

The civil war is fought between the descendants of King Viserys I’s two marriages. The two factions are defined by the colors worn by their respective queens: the black of Rhaenyra’s sigil and the green of Alicent Hightower’s dress at a pivotal feast.

Team Black: Princess Rhaenyra’s Line

Princess Rhaenyra is the designated heir, the "Queen on Dragonstone." Her lineage is complex, marked by a controversial first marriage and a traditional second marriage to her uncle, Daemon.

• Queen Rhaenyra Targaryen: Viserys’s daughter and heir. Dragon: Syrax.
• First Marriage (to Laenor Velaryon):
  • Jacaerys Velaryon (Jace): Eldest son, heir to Dragonstone. Dragon: Vermax.
  • Lucerys Velaryon (Luke): Second son, whose death by Aemond’s dragon, Vhagar, officially started the war. Dragon: Arrax.
  • Joffrey Velaryon: Third son. Dragon: Tyraxes.
  • Note: Though officially Velaryons, their true paternity is widely disputed, a key insult used by the Greens.
• Second Marriage (to Daemon Targaryen):
  • Aegon Targaryen (Aegon the Younger): Fourth son.
  • Viserys Targaryen: Fifth son.
  • Rhaena Targaryen: Daughter.
• Prince Daemon Targaryen: Rhaenyra’s uncle and second husband, a formidable warrior and dragonrider. Dragon: Caraxes. He is also the father of Baela and Rhaena from his previous marriage to Laena Velaryon.

Team Green: Queen Alicent’s Line

Queen Alicent Hightower is the mother of the usurper, King Aegon II, and the faction’s figurehead, supported by her father, Otto Hightower, the Hand of the King. They hold King’s Landing and the Iron Throne.

• Queen Alicent Hightower: Viserys’s second wife, daughter of Otto Hightower.
• King Aegon II Targaryen: Eldest son of Viserys and Alicent, crowned King upon his father’s death. Dragon: Sunfyre. He married his sister, Helaena.
• Queen Helaena Targaryen: Daughter of Viserys and Alicent, married to her brother Aegon II. Dragon: Dreamfyre. They have three children: Jaehaera, Jaehaerys, and Maelor.
• Prince Aemond Targaryen: Second son of Viserys and Alicent, a dangerous and powerful dragonrider who killed Lucerys Velaryon. Dragon: Vhagar (the largest living dragon).
• Prince Daeron Targaryen: The youngest son of Viserys and Alicent, often overlooked but a key player in the war. Dragon: Tessarion.

The children of Aegon II and Helaena—Jaehaera, Jaehaerys, and Maelor—are the current generation of heirs for the Greens, making them high-value targets in the ongoing Targaryen civil war. The tragic death of Prince Jaehaerys in Season 2 was a direct retaliation for Lucerys's death, escalating the conflict beyond repair.

The Dragonseeds and Bastards: New Branches of the Fire Blood

A crucial development in the latest season is the emergence of the "Dragonseeds," a term for individuals with some degree of Targaryen or Valyrian blood who attempt to claim riderless dragons. This development dramatically expands the effective family tree and introduces new, volatile entities into the war. The Blacks seek these new dragonriders to bolster their forces against the Greens, who possess the formidable Vhagar and Sunfyre.

The search for Dragonseeds involves the illegitimate children and distant relatives of the Targaryen and Velaryon houses. This concept of "fire blood" lineage is a key LSI for understanding the dynamics of the war, as it introduces commoners into the high-stakes political drama. The true nature of the Velaryon children's parentage (Jacaerys, Lucerys, and Joffrey) also remains a persistent, explosive entity within the political landscape, constantly used by the Greens to delegitimize Rhaenyra’s claim.

The Dance of the Dragons is a devastating civil war where every participant is related by blood, marriage, or both. The Targaryen family tree is the blueprint for the entire conflict, showing that the fiercest battles are often fought between those who share the same lineage. As the war progresses, the tree will continue to be pruned by tragedy, leaving only a few survivors to rebuild the dynasty.
