Varian, an erstwhile gladiator and current leader of the human kingdom of Stormwind, is the military commander of the Alliance.
Varian Wrynn is the current king of the human kingdom of Stormwind and military commander of the Alliance. In his younger years, Varian survived the ravages of the orcish invasion of Azeroth, the First War, ending with the assassination of his father, King Llane Wrynn. Years later, Varian reclaimed Stormwind City and initiated its reconstruction, marrying the beautiful Tiffin Ellerian and raising a son, Anduin, whom he named after the great Alliance hero Anduin Lothar. Long after the dust settled from the Third War, Varian was kidnapped by minions of the black dragon Onyxia, who split Varian into two separate beings: one embodying his strength and resolve, and one bereft of willpower. The dragon hoped to kill Varian's warrior qualities, yet still rule Stormwind by using the weaker king as her puppet. But Varian's stronger half escaped his captors, and earned a new name for himself as the legendary gladiator Lo'Gosh, the "ghost wolf."
After reuniting his selves and reclaiming his throne, King Wrynn organized the campaign against the Lich King in Northrend and defended his realm against the terrors of Deathwing's Cataclysm. In recent days, Varian has turned his eye toward his old enemies in the Horde, and many in his council fear that their king actually desires another years-long war between Horde and Alliance. Varian's ongoing struggle--to balance his warrior's instincts with his duties as a king--has only grown more critical in the wake of Theramore's destruction and the battle for the continent of Pandaria.
