The Orc tribe have wandered the land of the elements since ancient times, they don't care too much about constant wars between the kingdoms. They are characterized by nomads and proud warriors, when the great war broke out, the orcs refused to participate, they would not sell their sword to the highest bidder, you can only win the trust of a tribe in a fight to the death. All the kingdoms sent their best warrior to face the orc leader, to win the favor of the entire tribe.
The blood ran is day, the poor warriors of the kingdoms were not a rival. That same night the leader met one of his ancestors, who warned him that his people would be slaughtered, by the kingdom of fire. Running away is cowardly, but for the first time, the great orc chief felt fear, not of dying, but of seeing those he loves die.
They quickly began their escape, but the kingdom of fire was already underway. The leader guided his tribe into the lush forests. Where he was received with contempt for the spirit of the forest. He explained that the kingdom of fire would attack with a contingent that its people cannot overcome. The spirit of the forest I understand, but still I had to push them back, he asked them to leave, the leader refused and a battle began.
The great orc chief was winning, but he knew that beating the spirit of the forest would only bring more pain to his people. In a final act of saving his tribe, he knelt betraying everything he knew and his ancestors. Take my life, but let my people stay. The great spirit was moved and protected the orca tribe in their forests in exchange for their swords. Since then the orcs are no longer nomads fighting on the side of nature.
