Prologue
In the beginning, there was Chaos, father of all and of nothing. At first Chaos was not a sentient being, but over time Chaos became an intelligent force. Soon Chaos used this intelligence, he formed nine worlds.
First, was Asgard, home of the Gods. On this world many Gods and Goddesses took form. Second, was Vanaheim. A world of primal water, also where lesser Gods and Goddesses would live, rather than on Asgard. Third, was Alfheim. Home of the Light Elves and Good Spirits. Alfhwim is a world of light and air. Fourth, was Jotuinheim. A dangerous world of storms. Fifth, was Muspelheim. Home to the Killer Giants, a world of primal fire. Sixth, was Hel. The underworld where the dead are sent. Hel is ruled by the Goddess Hella. Seventh, was Svartalheim. A subterranean world. Eighth, was Niflheim. The shadow world. Ninth was Migard, home of the humans.
While Chaos had created the worlds, he allowed the other Gods and Goddesses to choose where they lived and what they would watch over. Soon the nine worlds were inhabited by other beings, created by the Gods and Goddesses watching over the worlds.
Migard, home of humans, was ruled by a group of Gods (Nuitari, Neru, Neptune, Kvasir, Njordr, Ullr, Vali, Loki, Tyr, and Thor) and Goddesses (Ran, Vor, Sol, Nott, and Eir). These Gods and Goddesses had worshippers. These humans were said to be "gifted" by a certain God of Goddess. The gods and goddesses rarely went down onto Migard, when they did, humans took it as a sign, a miracle if you will.
Now, the Gods and Goddesses knew that they couldn't interfere too greatly with the lives of the humans or they would face judgment from Chaos. However, when one, Ablus Dumbledore, tried to breach the barriers and he actually attempted to become a God, they reported to Chaos. When Chaos got word of this humans attempts to become a god, Chaos, for the first time since creating it, went to Migard, to punish a human.
