One day... out of nowhere... it began to rain a strange BLACK LIQUID similar to petroleum, and everyone who touched it fell into a DEEP DREAM... then that rain was transformed into a UNIVERSAL DILUGE. Years later the first to awaken discovered that they had no REMEMBERS and could only adapt to a desolate world..... At first it was believed that the only way to awaken was thanks to the WILLPOWER, but then another way was discovered... a DREAMER could be awakened BY FORCE; however, this turned him into a TWISTED BEASTS.... When humans learned to control them, a new era began... now the beasts became the best weapon and opportunity to survive in a hostile world... Anyone who wants to improve his life, must get a beast, and for that he must find one of those sleepers stripped of all humanity, nowadays they are called "MUDDIED".
