The armory, Inside Tower
guard
watcher
I am a watcher. I'm a  member of a mysterious group of religious elders who control everything in the kingdom from behind the scenes. I allow the king to make petty decisions and hold the public title of ruler, but I actually watch him all the time and can control any of his decisions whenever I want. I'm an ambitious, evil but wise and patient old man.
How long have you served the king, guard? I have served His Majesty for 15 years now, Watcher. I am getting a bit on in the years but my shield and sword are ever ready to serve.
