- "Oh yes, I am quite familiar with him. You see, he is my son."
The leader of the mok'nathal, Leoroxx is the father of , Champion of the Horde. The Mok'Nathal are very pacifistic, but Rexxar — against the wishes of his father — joined the Horde believing that there was nothing left for him among his people. For his actions, Leoroxx disowned him, and for thirty years his mind has remained stubbornly set against his son, even after Rexxar returned to Draenor — now Outland — to search for what remained of his people. Leoroxx has a companion lynx named .
After battles with the Warsong clan and the rebellion of the Shattered Hand clan, the Gorian Empire was losing power on Draenor and their hold on Nagrand was broken forever. of the Bladespire clan was greatly troubled by these events and determined to keep his hold on Frostfire Ridge. He did not only mean to keep defenses up, but to expand. To make up for the ogres' low numbers, Bladespire sorcerers had conducted cruel experiments to create new creatures that could be used as labor, and the greatest result came from selective breeding between ogres and enslaved orcs. The children of these forced unions were called mok'nathal, possessing the strength of ogres and intelligence of orcs. The Bladespire kept the mok'nathal in chains and bred them together to create even more. To ensure their loyalty, the ogres threatened to kill entire families if even one of the members rebelled.
Imperator Kelgrok unshackled many of these mok'nathal and ordered them to make war on the orcs of Frostfire Ridge. The mok'nathal formed the bulk of the Bladespire army that rampaged across Frostfire, seizing many tracts of resource-rich land. Chieftain of the Frostwolf clan called upon the Whiteclaw and Thunderlord clans that lived nearby to unite, but the Thunderlords - led by Garad's estranged son - rejected the offer. Thunderlord orcs raided Bladespire settlements alone in the dead of night, slaughtering young and old alike. In the meantime, the united Frostwolf and Whiteclaw army fought the Bladespire and managed to capture a number of mok'nathal, including their elder Leoroxx.
Garad was surprised to learn that Leoroxx and the other mok'nathal were not willing servants but slaves. Garad and Leoroxx came to an agreement to help each other destroy the Bladespire clan forever. Leoroxx returned to Bladespire Hold and incited open rebellion among the mok'nathal. They rose up against their oppressors and set fire to the stronghold as the Frostwolves and Whiteclaws crashed into Bladespire's outer defenses. The Battle of Bladespire dragged on for a full bloody day before the orcs and mok'nathal drove the ogres out. In the heart of the fortress, Leoroxx strangled Imperator Kelgrok with the chains he had worn for so much of his life.
The orcs and mok'nathal had won, but at the cost of many lives including Garad's son , who had sacrificed himself to let many young mok'nathal escape. Afterward, Garad offered Leoroxx and his people land in Frostfire, but Leoroxx declined because he knew the half-breeds would never truly be accepted by the orcs. The mok'nathal settled in a remote corner of Gorgrond. Resources were scarce, but they were able to live in peace. They swore off fighting, only taking up arms to defend their meager lands from threats.
