Imperator Hok'lon

Imperator Hok'lon was the sorcerer king of the Gorian Empire roughly 100 years before the opening of the Dark Portal. Outraged by the newly arrived draenei's construction of Shattrath City atop the ruins of the ancient ogre city of Goria, he led a brief and entirely unsuccessful campaign to reclaim the area and died in the attempt.

Biography
The ogres had been aware of the draenei since the day they arrived on Draenor, roughly 100 years before, keeping close watch on their expansion across Terokkar Forest. When the draenei had first began to construct the city of Shattrath atop the ruins of the ancient ogre city of Goria, there was an explosion of anger within the current ogre capital, Highmaul. It was seen as a unforgivable insult for these small, weak newcomers to build a city on the bones of the Gorian Empire's great capital, but Shattrath's sleek construction and otherworldly defenses gave the ogres pause. Nothing like their technology had ever been seen on Draenor before, and even their weakest apprentices had more refined and effective magical techniques than even the most advanced ogre sorcerers.

Hok'lon, himself a gifted arcanist, seized control of Highmaul and declared that he would conquer Shattrath. He believed that the draenei had stolen their power using hidden knowledge left beneath the old capital. Hok'lon incited his people to wage war by publicly sneering at the draenei, which he called "usurpers", and promised that Highmaul would become the center of a new, enlightened Gorian Empire once the draenei had been slaughtered. The draenei had even already rebuilt their city for them. Highmaul's aristocracy, eager to claim the new city for themselves, threw their support behind Hok'lon.

The ogre army that marched on Shattrath vastly outnumbered the draenei, but the city's defenses easily repelled their first — and only — attack. As the ogres regrouped, Rangari and Vindicators launched surprise attacks from multiple directions. The Vindicator Akama led an elite force of holy warriors that included two of his greatest followers, Maraad and Nobundo. They found and killed Hok'lon and his generals, leaving the ogre forces in disarray. Rather than slaughter their foes, the draenei then immediately returned to Shattrath. The draenei leader, Velen, appeared on Shattrath's ramparts, wreathed in the Light and speaking with a voice that rumbled through the heavens: "Go home, and you will not be harmed". The ogres fled. The grandiose war that was meant to revive the Gorian Empire had fallen after one attack, and the Highmaul ogres never attempted a frontal assault on the draenei again.
