Appearance and Character
A Dance with Dragons
Tumco spends most of A Dance with Dragons in training in the Great Pyramid to become a knight, as a squire to Ser Barristan Selmy. Strong and fast, the youth already has a good acquaintance with sword and battle-axe. Barristan thinks Tumco shows much promise as he is the best natural swordsman he has seen since Jaime Lannister. Along with Larraq he is Barristan's best squire.
The Winds of Winter
This information has thus far been released in a sample chapter for The Winds of Winter, and might therefore not be in finalized form. Keep in mind that the content as described below is still subject to change.
On the brink of battle against the Yunkish besiegers, Tumco carries the banner of House Targaryen. Barristan realizes that Tumco is more afraid of the Pale Mare - spreading through the siege camps and launched into the city via trebuchet - than he is of their foes.
