It reminds me a little of Game of Thrones, where all the major players, the royals etc all have spy networks. This is a world where very poor peasants and servants are everywhere and many of them, including children, end up in the employ of this person or that person, watching who is coming and going and reporting back, such that one’s movements and meetings are trackable to a minute degree. The better your spy network, the more power you have.

Of course Varys, spymaster to the crown, is famed for the effectiveness of his network, which spans the continent and even across the sea to other major cities.

He himself is a master of disguise. This was left out of the show entirely but he frequently appears by surprise, whipping off the guise of an old woman and later leaving the scene dressed as a priest, etc. He grew up with actors and uses makeup and costume changes to hide his tracks. He can change his voice and gait at will and routinely shocks people by his ability to blend in and appear or disappear at will. He knows how to leave a place by a different entrance than he came in, and knows all the secrets passageways of the castle.

Basically, in a world with no privacy, the world’s foremost surveillance master is a model for all of us in these times. If you want to move freely in public but do so without a trace, be prepared to pull your hood up and when you leave a restaurant, take off the hoodie you were wearing when you went in. Practice different postures to throw off gait tracking.

You don’t have to like it, but this is the world we live in.
