Icefall Yhetees are some of the coldblooded monsters of the Mortal Realms that follow the Beastclaw Raiders. These simian snow born horrors and white-skinned killers come from ice covered mountains and wide tundras, following the raging snow storms of the Beastclaws. The deathly cold they spread is so strong that it leads some to claim their armor and weapons freeze up and become heavier covered in ever-growing layers of frost. They attack their enemies covered in snow, knowing that it's at this moment of helplessness that their enemies are most vulnerable.
The origins of the Yhetee remain shrouded in mystery - they are speculated to be anything from descendants of Ogors abandoned and remade by the magic of the Everwinter to being born from the gales of the harsh winds themselves, pouring forth from the frozen depths. The Weirdnob Shamans of the Icecrackas Warclans believe them to be the divine children of Gorkamorka himself. Whatever it may be, the Yhetee do not speak of it - indeed, their language is eldritch and strange, spoken only by the Huskards. 
For all of their silence, the Yhetees are deadly foes. They howl and lope through the snow at the speed of a howling blizzard. The Ogors, feeling some distant kinship with them, leave them to their business, only grumbling at their tendency to deep-freeze food. They wield crude clubes, axes and poleaxes made of stone covered in a thick, magical hoarfrost, that appear on their hands seemingly out of nowhere.  No matter the temperature, these weapons will not melt - even in the Realm of Fire's parched lands opponents will find their breath steaming and blows sluggish before the Yhetees - a fact their savage foe will take full advantage of.
