The Half-Orcs are the direct result of ancient Human and Orc alliances. These alliances have been broken long ago, but the Half-Orc race endures and they are somewhat accepted amongst both the human and orc civilizations.
The Rārkai is a tribal group of nomadic Half-Orcs who have renounced their relation to the Orcs and Humans. Their appearance and physical characteristics are the same as the Half-Orcs but their belief system and mentality are much different. The Rārkai are peaceful in nature and have a strong spiritual energy. They have adopted the role as guardians of mother nature and their faith resonates with a strong moral foundation for the will of good. They trust the spirits of the land and often turn to them for guidance.
