The tale of the two worlds

There were two worlds, known as the Monster World and the Mythical World. In those worlds lived the humans, creatures, and anthros. The three species lived together for many years, in harmony and friendship. But, the humans began to be filled with greed and broke the ancient bond between man, creature, and anthro. The other two species became slaves to the humans, forced to do their bidding. They were killed, beaten, and later, were experimented on due to the evil curiosity of the human mind. Many harsh years passed, but then someone, a slave to a human family, began to hear the whispers of the stars, and began a rebellion. They were granted an awesome power, and with the aid of others, they began to liberate the oppressed. They humans were soon wiped out, never reaching their paradise. Some human souls were chained to the worlds, becoming the silent ones while some with cruelty in their hearts, became vicious demons. The liberated rejoiced and praised their creators's name. The creators then bestowed upon the anthros and creatures the 13 elements, along with their protectors, the elemental Guardians, so that they were able to protect themselves. Years have passed as the citizens of the two worlds have rebuilt and spread themselves across sea and land. But they cannot rest easy, for the dark spirits of the Shadow Lands threaten to steal the souls of the innocent and destroy the light of the stars. The stars, being as strong as they are, shall fight the darkness to protect it's children, but if they cannot match with the strength of the shadows, they may whisper   to someone with a valiant and true heart , and bestow a destiny to them. It only matters on who would listen to the stars.
