Jaesse Lannister

Jaesse is an albino, thus milk-white skin and blood red eyes. Jaesse is the eldest son and heir to Lord Trevan Lannister and Lady Rhaenyra Targaryen.

From young he has a close relationship with his twin, Visenya, and cares for her deeply. He is also skilled with swords from a young age.

Blood and Fire
Jaesse, together with his parents and sister Visenya, are invited to King's Landing for a feast, at which he and his sister are betrothed to the Starks. He is betrothed to Lyarra Stark.

Jaesse is seen practising in the yard in King's Landing with Aerion and other squires when Viserys passes by.

After Viserys Targaryen is poisoned at that feast and Elayne Stark is arrested, Visenya visits him in his bedchamber and expresses her concerns for their betrothals. Jaesse suggests that they change the betrothals, and Visenya replies that Jaesse is stupid. Jaesse questions if Visenya wanted to be queen, Visenya admits that she does. Jaesse tells her to leave the rest to him.

In the days of tourneys that followed, Jaesse unhorsed all his opponents and crowned Rhaena Targaryen as the Queen of Love and Beauty. Visenya looks visibly disturbed, but Jaesse smiles back at her and she looks away.

He visits Rhaena in her bedchambers and asks her for a favour: To please the king so that he might change the betrothals. He knows that now that Elayne Stark is arrested, the Starks may be seen as traitors, and would have been if not for Cregan Stark being the king's best friend, and the betrothals that had bound Houses Stark, Lannister and Targaryen.

Skills
Jaesse is a skilled sword fighter, and wields a gilded steel bastard sword that he names White Blood. He won his first tourney against other knights when he was thirteen, then subsequently won other tourneys as well.

He is incredibly skilled with swords, and developed his own style of wielding a longsword in his right hand, and a dagger in his left. He can wield dual swords fairly well, though he is best with a single bastard sword.
