From the preview:
Living among the high valleys and the foothills, these tribes of Ogres have been an integral part of the Halodyne culture since its inception and are a vital component of Halodyne warbands.
The Cornucopian Mountains form a border around the Halodyne lands, and so the hill-tribe ogres are often the first affected when enemy raids or an invasion takes place.
Besides that, the mountains are rife with a plethora of deadly beasts.
No wonder then that the Hill Ogres are exceedingly capable in melee, wielding deadly two-handed falxes.
