Warcraft III: The Frozen Throne
Previously led by Sen'jin on the Broken Isles. Rokhan has joined forces with war chief Thrall when he rescued them from the sea witch, Zar'jira, and send them to the barrens of Kalimdor. After the clash of Mount Hyjal, the jungle trolls settled on the Echo Isles off the coast of Durotar, where it was named after Durotan, but Rokhan went to Orgrimmar as a troll scout for Thrall. When the beast master, Rexxar, traveled to the orc encampment in Ogrimmar with the message from Mogrin, Thrall requested him to assist Rexxar's trek through the wilds.
Rokhan and Rexxar found the human forces of Kul'Tiras on the coast of Durotar after they went to the observatory in Gar'thok's Outpost, and when they reported to Thrall, he sent them back to look for the outpost ruined, and the Kul'Tiras quiet hostile.
Rokhan began to worry about his known people on the Echo Isles, and thought that perhaps they would go to the mainland to avoid risks. Thrall agreed to send Rokhan and his band of the Horde to the Echo Isles, warn Vol'jin, son of Sen'jin, chieftain of the Darkspear tribe, and rightful ruler of the Echo Isles, and see them off the island.
After eliminating various Alliance battleships that blocked their path as obstacles and lighting signal fires for the outlaying village, both Rokhan and Rexxar came to a summit in Thrall's encampment. When they were surprised by the attacks of Kul'Tiras, Thrall wanted his hope in finishing things peacefully to send Rokhan and his lads to Theramore Island to parlay with Jaina Proudmoore in a secret matter.
With Jaina Proudmoore's help, both Rokhan and his friend Rexxar discovered the human invaders, led Admiral Daelin, who was determined to clear out the orcs in Durotar. He fought alongside Rexxar as they hastily traveled around the barrens of Durotar enlisting aid from their allies of the Horde. Both the Human Alliance and Orc Horde forces lastly fought in a titanic battle at Tidefury Cove, and when the Horde emerged victorious, they chased the Alliance back to the town of Theramore. Rokhan supported to send a Blaze of Glory on Theramore, and defeated Daelin's naval elite forces beside Rexxar. After the defeat of Daelin Proudmoore and the end of the war between the Horde and the invading Kul'Tiras, Rokhan was honored by his people and Thrall's Orcish Horde.
Tensions remained high between the good orcs of Durotar and the humanity of Theramoore. The war nearly broke out due to the scheming of Zmodlor, the minor demon, and a few cultists of the Burning Blade. Rokhan was still in service of Thrall as a scout and made a sudden appearance to warn the Warchief of reinforcements to Northwatch Hold on the territorial border between Alliance and Horde races. Rokhan is described as a surprisingly gentle face for a jungle troll with kind eyes. He was rumored to, and still may have been sent on an important mission given by Vol'jin.
