Viserys I Targaryen.

Shortly after Queen Aemma Arryn had died in childbirth due to Viserys' decision to save the child, and the latter died a day after his mother. The court was filled with incessant murmurs, advising King Viserys to take another wife to have a son despite the fact that the King had already proclaimed his daughter, Princess Rhaenyra as his successor.

Many lords and nobles had begun to move on the board so that their sisters or daughters would be queens and their blood would sit on the iron throne, even the Hand of the King, Otto Hightower had thought of sending his daughter to console the King with his losses so that she would win his heart. However, no one expected that it would be Princess Rhaenyra herself, who would take a beautiful young woman to the fortress for her father to take her as a wife, and thus ensure his succession.

Viserys has been widowed and Rhaenyra has brought her pawn to the fortress to ensure his succession.
