Harrold is one of the longest-serving members of the Kingsguard. He was once a powerful knight with a successful military background. Named to the Kingsguard during the reign of Jaehaerys I, he eventually succeeded Ser Ryam Redwyne as Lord Commander. King Viserys has assigned him to Rhaenyra Targaryen as a sworn shield.
Behind the scenes
Harrold Westerling was revealed to be a recurring character in House of the Dragon on December 8, 2020. On September 24, 2021, HBO announced that Graham McTavish had signed on for the series. The character breakdown reads as follows:
- "Ser Harrold has served in the Kingsguard since the days of King Jaehaerys; he is a paragon of chivalry and honor."
In the books
It is unclear how Harrold is related to Johanna Westerling, who marries Lord Jason Lannister to become Lady of Casterly Rock and a fairly prominent recurring character.
Harrold Westerling actually died of old age in the middle of Viserys's reign, two years before the wedding of Rhaenyra and Laenor - yet teaser trailers for House of the Dragon clearly show him alive during events set after the time skip to the adult versions of the characters. Thus the TV-version of Harrold seems to have been condensed together with aspects of one or two of the other Kingsguard members in this time period.
Coincidentally, in the books both Harrold Westerling and Grand Maester Runciter died within months of each other, after which Mellos was appointed to replace Runciter - and thus Harrold never met Mellos. Teaser trailers have revealed that the TV version merged Runciter and Mellos into one character named "Mellos", who is therefore Grand Maester at the beginning of Viserys's reign. The result is that "TV-Mellos" has been expanded to appear earlier than he did in the books, while "TV-Harrold" has been expanded to appear later than he did in the books, and they now overlap with each other. The second teaser trailer clearly shows Mellos and Harrold standing next to each other at an event early in Viserys's reign.
