A Time for Unicorns

There was a time when unicorns roamed the earth. They were pure and unjudging. They let humans take reign upon the world and control them, cage them, hunt them, until there were no more unicorns left. Without them, the world became a barren wasteland. Leftover population of humans tried creating unicorns. But they were not as pure as the real ones and soon turned against their creators. Half machine, half horse, the meckacorns ruled the land until one day...when it seemed the world could produce no more living creatures...the time of unicorns is once again reborn!
