Tycho Nestoris is a representative of the Iron Bank of Braavos.
Tycho Nestoris is a tall, gaunt stick of a man with long legs and a beard as thin as a rope from his chin and almost reaching his waist. He has a narrow face. He wears a brimless three-tiered hat of purple felt, robes of a sober purple trimmed with ermine and a high stiff collar.
A Dance with Dragons
Tycho is sent to the Wall to negotiate payment of the debt of the Iron Throne with King Stannis Baratheon. He comes to Eastwatch-by-the-sea with three ships and then travels to Castle Black with Queen Selyse. Jon Snow negotiates with him for the use of his ships for a voyage and a loan to purchase food for the winter while the Night's Watch provides him guides to reach Stannis, who has left Winterfell.
Tycho travels to Deepwood Motte, where he pays a ransom for the ironmen which Lady Sybelle Glover accepts for the king. He then goes through the snow toward Winterfell looking for Stannis. The king is not there, but Tycho finds Mors Umber outside the gates with some green boys. He takes Theon Greyjoy and Jeyne Poole, who were there after their escape from Winterfell. After three days they arrive at Stannis's camp in a village.
The Winds of Winter
Tycho is brought before Stannis and the two sign an agreement, with Stannis acknowledging the Iron Throne's debt to the Iron Bank and Nestoris agreeing to loans to Stannis. Stannis has Ser Justin Massey escort Tycho and "Arya Stark" back to the Wall. Then, Justin is to accompany Tycho back to Braavos.
