The Winterax tribe are a tribe of ice trolls, once part of the nation of Zul'Drak, led by Korrak the Bloodrager. After the Sundering, the Drakkari tribe continued to live in what had become the bitterly cold continent of Northrend. The Winterax and Frostmane tribes, however, later settled in the Eastern Kingdoms. Due to the ice trolls' unrelenting hostility toward outsiders, historians have yet to learn how these two tribes were separated from the Drakkari and came to live so far from the ancient site of Zul'Drak.
Then one day Korrak and his people simply disappeared, along with most of their belongings and supplies. The mystified orcs and dwarves concluded that the trolls had at last given up their home, which, after all, had devolved into little more than a bloody battlefield, and left in search of greener pastures. Korrak has recently been seen competing in the Amphitheater of Anguish as one of the top gladiators. As to where the rest of his tribe is unknown, but one can speculate that they have rejoined with the Drakkari.
