Lord Varys, also called "the spider", is a member of the king's small council. As member of the small council, he serves as the Master of Whisperers, the King's foremost spymaster and intelligence agent. He holds no inherited title, castle or lands in Westeros, but is called "Lord" as a courtesy due to his position on the council, which traditionally is made up of high lords.
His sophisticated intelligence network - one of the largest in the world - spans both Westeros and Essos, as far as Vaes Dothrak and even Qarth. He refers to his agents and sources of information as his "little birds". One of his jobs is to keep an eye on the movements of Viserys and Daenerys Targaryen and ensure they do not become a threat to King Robert's reign.
