Dragons in the world of Game of Thrones have a sacred bond with their riders, as we’ve seen throughout Game of Thrones and in House of the Dragon’s sixth episode, “The Princess and the Queen.” Targaryens are synonymous with the legendary beasts, but there’s also more to learn about House Velaryon’s history as dragonriders, of which Princess Laena was the most recent and beloved. Her dragon Vhagar has an even greater history in A Song of Ice and Fire. Vhagar was the second-largest dragon known to Westeros, following Balerion The Black Dread, with a throat so large, a horse could ride down it and a fire so hot, it could cook knights in their armor. Born in what was called The Century of Blood following the cataclysmic event that destroyed Valyria and left a power void in Essos, Vhagar was first claimed by Visenya Targaryen, the older of Aegon the Conqueror’s sisters/wives. (Yup, the Targaryens have always been like that.) Visenya rode Vhagar into battle all over the Seven Kingdoms during Aegon I’s campaign, roasting strongholds in the riverlands, the Trident, and most – but not all – of Dorne in the name of House Targaryen. Vhagar wouldn’t return to Westeros for several years, but when she did, it was with Visenya, Balerion, and her dragonrider Maegor, making their deadly claim to the Iron Throne and burning more villages, as per Game of Thrones custom. Aenys had abandoned King’s Landing in the ensuing rebellion and fled to Dragonstone, where he died of illness. The path was cleared for Visenya to place Maegor on the throne, where for good reason he would be remembered as Maegor the Cruel. After Visenya’s death, presumed to be of natural causes, Vhagar remained unridden for nearly thirty years. Do dragons mourn? It can sometimes appear that way (look to Drogon and Rhaegal seemingly roaring with grief after witnessing Viserion’s death at the hand of The Night King.) After Balerion’s death at the respectable old age of two hundred, Vhagar was the last living original Targaryen dragon from Aegon’s Conquest and the veteran of hundreds of successful battles. She eventually took residence in the dragon pits of King’s Landing until she met her next dragonrider, the young Laena Velaryon. Laena reveals to her daughter Rhaena in “The Princess and the Queen” that she first rode Vhagar when she was 15 years old. In House of the Dragon’s second episode, an even younger Laena expresses an interest in Vhagar’s whereabouts, suggesting that she’s always been fascinated with the big beast. Unfortunately it seems that Vhagar was sadly destined to grieve again, as the bond she shared with Laena was not born of fire and blood, but was a relationship celebrated and beloved by all who witnessed them on their joy rides around the world.
