Lord Tzao

Tzao is a mogu warlord of the Shao-Tien Clan, who has since entered self-imposed exile from his brethren. An imposing figure who once held a position of great influence among his people, Tzao embodies the strength and cunning of any true mogu, while carrying the same fervent loyalty to the Titans as the clans of old.

Following the parting of the mists and Lei Shen's resurrection, Tzao served as a fearsome lieutenant in the Thunder King's armies. While his army was crippled following the assault on the Throne of Thunder, the warlord escaped with his life and swore he would see his king avenged. Performing guerrilla attacks on pandaren settlements throughout the Vale of Eternal Blossoms, he only ceased aggression against his foes when the common threat of the Burning Legion emerged.

As the Legion's third invasion came to an abrupt end thanks to the Pantheon's intervention, Tzao watched in awe as the Dark Titan was finally defeated. At that moment, the mogu had an epiphany: the Titans were not dead, nor had they forsaken Azeroth as the Thunder King believed. Without so much as a second thought, he cast aside his position of power in the clan and left to ponder the mysteries of the universe,

Arclight's first encounter with Tzao occurred in the Vale, around a month prior to the outbreak of the War of the Thorns. Carrying a series of titan discs from the Prison-Vault of Uul'zuggath, the gnomes set out to fulfil the vault's caretaker's final demand: deliver its legacy to its parent facility under the Vale of Eternal Blossoms. Tzao reluctantly offered his assistance with the task, seeing that he and Arclight shared a common duty to the Titans.

Tzao's assistance allowed the gnomes to enter the Pools of Power underneath the Vale, helping them navigate the Guo-Lai Halls to steal a key from his former allies. Once the job was done, the mogu returned to solitude, but not before demanding a tribute for his assistance. Ozisus Warpwrench volunteered a Golden Doctor Boom Hearthstone card, which the exiled warlord amusingly accepted despite being unfamiliar with the card game.

Months later, Tzao would resurface in Zuldazar on a personal mission to destroy the remainder of Zul and Warlord Kao's forces. He would briefly work with Arclight again, seemingly sacrificing himself to save the gnomes from Zulian loyalists. However, in a remarkable feat of strength, Tzao fought off all of the adversaries alone as Arclight fled.
