Core Lineage: The Targaryen Bloodline
Viserys I and the Heirs
Viserys I Targaryen begins the season as king. His claim passes first to his daughter Rhaenyra (named heir), then to his sons by Alicent, Aenys and later Viserys II. Birth order and gender drive succession disputes, with Rhaenyra representing the elder line and Alicent pushing her own sons as rightful heirs. Marriages further complicate claims, as each union binds a house to a faction.
Rhaenyra’s Line
Rhaenyra marries first Laenor Velaryon, then Daemon Targaryen. With Laenor she has sons Jacaerys and Lucerys; with Daemon she adds Joffrey. Her younger sons by Daemon, Luke and Joffrey, are teenagers whose allegiances influence military outcomes. Rhaenyra’s claim depends on her sons and her control of dragons, notably her dragon Syrax and her sons’ dragons, who shape battlefield dynamics.
Alicent and the Greens
Alicent begins as queen consort and becomes the pillar of the opposing claim. Her children with Viserys I—Aemond, Helaena, and the late Jaehaerys—constitute the younger line, known as the Greens. Aemond loses an eye early; his ambition and rivalry with Luke escalate conflict. Helaena’s role is more passive, often caught in court maneuvering. This family structure sets up enduring grudges and war aims that persist beyond Season 1.
Marriages, Alliances, and Consequences
Marriages in the show are political tools, and each union has consequences. Rhaenyra’s marriage to Daemon strengthens her faction with experienced leadership and dragonpower. Alicent’s children marry into influential houses, expanding the Greens’ reach. The Velaryon and Baratheon unions create mixed loyalties, while the Hightower connection amplifies the Greens’ influence in Oldtown. These bonds determine where fleets, swords, and counsel are committed.
Notable Bloodline Outcomes by Season 1 End
By the close of Season 1, the family tree has already shaped the war’s direction. The elder line’s claim is clear, but so is the Greens’ resolve. Important deaths and survivals influence morale and legitimacy. The following table outlines key figures, their fate at the end of Season 1, and why it matters for the succession.
| Figure | House/Faction | Outcome at End of Season 1 | Why It Matters |
|---|---|---|---|
| Viserys I Targaryen | King (Greens) | Gravely ill; legitimacy contested | Succession hinges on his death |
| Rhaenyra Targaryen | Heir (Elder line) | Leaves King’s Landing; claim recognized by some | Physical and symbolic loss of seat | Greens | Injured; vows revenge | Motivates future hostility toward Rhaenyra’s line |
| Daemon Targaryen | Rhaenyra’s faction | Active commander; more aggressive | Brings military experience to the elder line |
| Lucerys Velaryon | Rhaenyra’s line | Sent on diplomatic mission; danger increases | Highlights growing instability in the realm |
| Corlys Velaryon | Velaryon | Injured and grieving | Undermines the navy’s short-term strength |
Relationship Map: How Characters Connect
Visualizing relationships helps you follow conversations and allegiances. The core map includes parent child links, spousal ties, and key alliances. Use this shorthand to track who stands where as plots thicken.
- Viserys I is the root: his children Rhaenyra (eldest) and Alicent’s sons form competing branches.
- Rhaenyra + Daemon = experienced leaders united by cause; their children extend the elder line.
- Alicent + Viserys I = the Greens; Aemond and Helaena are central to their strategy.
- Velaryon houses two branches: Corlys and Rhaenys support Rhaenyra; Vaemond represents dissent.
- Baratheon houses show divided loyalties that could shift with offers or threats.
FAQs
How do I track who is related to whom?
Start from Viserys I as the common ancestor. His children and their offspring define the factions. When in doubt, ask: Is this character aligned with Rhaenyra (elder line) or Alicent (Greens)? Marriages link houses and can change short term allegiances.
Who holds the strongest claim by the end of Season 1?
Legally, Rhaenyra as Viserys I’s firstborn remains the recognized heir. However, the Greens control the court and the nursery of future kings. The show frames the conflict as both legal legitimacy and raw power, so claims are strong but contested.
Do dragon riders decide the family standings?
Dragons heavily influence outcomes, but they do not automatically decide claims. Rhaenyra’s dragon Syrax and her sons’ dragons give military advantages, while the Greens counter with numbers, politics, and strategic marriages. Dragons shift battles; claims shift with courts, inheritances, and alliances.
Are marriages in the show consistent with the lore?
Yes. Marriages reflect House Targaryen’s historic practice of keeping bloodlines pure and consolidating power through alliances. Key unions, such as Rhaenyra with Daemon and the Velaryon ties, are faithful to the established family lore and drive the season’s conflicts.
Where can I find visuals of the family tree with names?
