The late Tang is a chaotic age: regional warlords carve up the land, eunuchs wreak havoc at court, and the emperor is forced into exile.
Amid the snow and wind beyond the frontier, an iron cavalry force known as the Great Snow Dragon Riders charges through the smoke of war. Li Guan, a lone loyal minister, carries a secret imperial decree thousands of miles to come to the emperor's aid.
With 100,000 soldiers in white armor and silver-tipped spears, he fights at Tong Pass, secures Chang'an, sweeps away the warlords, and reunites the realm. He rises from a fierce frontier general to the Grand Marshal of the Armies, with power over the entire court.
He had only wanted to be a loyal subject in a chaotic age and defend a corner of the realm. But the emperor's intentions are impossible to read, and his achievements threaten the throne. The executioner's blades are already at his neck.
When the entire court wants the loyal minister dead, and 100,000 cavalrymen kneel and beg him to march against the traitors, he finally raises his blade and rides into battle:
Cleanse the court of traitors, save the nation from peril, and turn a lone minister into a warlord of legend!
Let history judge his rights and wrongs, his merits and failings, alongside the Great Snow Riders through the ages.
