King Terenas formed the Alliance of Lordaeron, led by Anduin Lothar. The Second War saw the retaking of the orc held lands. Lothar died in the process, but Varian was now King of Stormwind. He was just 18 years of age. He was an active king, travelling around his kingdom to protect his people from orcs and other threats. He married Tiffin, who bore him a son. Anduin Wrynn was named for Anduin Lothar.
THE THIRD WAR
Following his ascension to the throne and the restoration of Stormwind, Varian faced a number of challenges. The Alliance of Lordaeron had begun to fracture, with no foe to face. Quel'Thalas, Stromgarde and Gilneas seceeded. Varian remained loyal to Terenas, however. The bond forged during the time he had spent in the north would not be easily broken.
At the same time, Stormwind faced internal strife. Stonemasons, led by Edwin van Cleef, had undertaken the work to restore the city. A price had been agreed upon. However, the House of Nobles who helped Varian lead Stormwind, were reluctant to pay it. The political structure was such that Varian could not simply overrule them and Lady Katrana Prestor led opposition to him. His frequent trips around the kingdom had left the House of Nobles in a position of power and he found himself the negotiator.
Varian's wife, Tiffin, supported the Stonemasons cause to her husband. Despite their best efforts, the pay handed over was far less than had been agreed. The Stonemasons Guild rioted in the streets. During the riot, a stone hit Tiffin and she was killed. Van Cleef ran and Varian had lost another loved one.
Varian did his best to remain a good king and was loyal to his alliances. During the Third War, he sent troops to support Lordaeron against the scourge and gave succor to her refugees. His support was to no avail. His long time friend Arthas, corrupted by his seeming inadequacy against the scourge and the legion, fell. Arthas had found himself lacking in comparison to those he kept company with, but had been unwilling to admit it. The nobility and prowess of Varian was just another of those comparisons. Arthas murdered his father, Terenas, and became the Lich King. Varian became leader of the Alliance and Stormwind the centre of human strength on Azeroth.
During the classic version of World of Warcraft, Varian is missing. A trip to the citadel would find only a young Prince Anduin, surrounded by his advisors - Bolvar Fordragon, the Regent-Lord and Lady Prestor.
Through quests, the player discovered that the king had been travelling to Theramore when he was abducted by the Defias. A spy within Stormwind had passed them details of his route. He was taken to Alcaz Island and held captive. He managed to escape, but the route was difficult. Varian was washed up on the shores of Durotar with no memory of who he was.
