Guardian Heroes

A supreme being created the universe to find ultimate warriors to hire as its personal soldiers. A vicious battle was waged between the Earth and Sky Spirits. The Sky Spirits bestowed incredible powers upon the humans, effectively making powerful wizards for their own gain. The human wizards joined the effort against the Earth Spirits, banishing them into the darkness. Soon after this was accomplished, the Sky Spirits grew fearful and jealous of the humans, and banished them all into the darkness with the Earth Spirits. Mankind instead opted for a more physical approach to life, and the Time of the Sword began.
