Tycho Nestoris

Tycho Nestoris was a banker and employee of the Iron Bank of Braavos. During the War of the Five Kings, he approved a loan to King Stannis Baratheon, enabling him to launch his ill-fated northern campaign. He later received Master of Coin Mace Tyrell in order to renegotiate the Iron Throne's position with the Iron Bank. Tycho was then made envoy to Queen Cersei I Lannister, giving her a new loan to purchase the Golden Company after she paid off the Iron Throne's previous debts from the spoils of Highgarden. Tycho was killed in the Sack of Braavos during the War of the Narrow Sea.
