Although his role is yet to be revealed, fans have been quick to try and work out who McTavish will play. As reported in the Radio Times, the actor was “spotted in full costume on the House Of The Dragon set in Cornwall, sparking rumours he would be playing Harrold Westerling, the lord commander of the kingsguard.”

Explaining more about the character, the report describes him as: “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.”
