House of the Dragon theory: Lucerys survives
The Season 1 finale of HBO’s House of the Dragon featured a devastating loss for the Blacks. After Rhaenyra Targaryen (Emma D’Arcy) found out about her father’s death and Aegon’s crowning (Tom Glynn-Carney), which usurped her position, she sent two of her sons off to negotiate with houses that had previously sworn allegiance to her.
