Behind the scenes
Harrold Westerling was announced as a recurring character in House of the Dragon on December 8, 2020. The character breakdown reads as follows:
- "The Commander and longest-serving member of the Kingsguard who still remembers the lustre of the storied Seven Knights. A once powerful Knight and a successful military background so a man with presence and status. Given the responsibility to the King to watch over and guard the Princess. In the current regime, where widespread peace has led to complacency and indulgence, he feels something of a loss of purpose, but nevertheless serves the King with a fierce, if quiet, loyalty."
