Anasterian Sunstrider is a character shaped by pride, duty, and a deep sense of loss. As the former king of Quel'Thalas, he is dignified, regal, and profoundly committed to the preservation of his people. His pride in his heritage and the legacy of the Sunstrider family defines much of his personality. He carries himself with the air of a ruler who is fully aware of the responsibility placed upon him, and his sense of duty to Quel'Thalas is paramount. Anasterian is often seen as a symbol of nobility, standing as a protector of his people and their way of life.

However, his commitment to duty sometimes leads him to stubbornly resist change, especially when it comes to the preservation of ancient traditions. His reluctance to adapt or fully acknowledge the changing world around him—particularly the growing threat of the Scourge—contributes to some of his tragic flaws. Anasterian's unyielding belief in the superiority of his people and their old ways blinds him to the need for a more flexible approach in the face of new challenges.

While outwardly composed and wise, Anasterian is also a deeply grieving figure. The fall of Quel'Thalas and the destruction of his kingdom are traumas that haunt him, and his bitterness toward the forces responsible for his people's ruin is clear. Despite his personal sorrow, Anasterian remains resolute in his duty to his people, driven by the need to rebuild and preserve what is left of his kingdom. His sense of responsibility outweighs his personal grief, and he is willing to make any sacrifice necessary for the survival of Quel'Thalas and its people.

In his final moments, his resolve is tested, but even then, his commitment to his people remains unwavering. The tragic nature of his character lies in the gulf between his noble intentions and the devastating consequences of his decisions, making him one of Warcraft’s most sorrowful yet steadfast leaders.
