Year before humans conquered the land. There was this 2 siblings named Luna and Anox. Daughter of the nature who guided the land from space creature who wanted the Earth for their existence. As the Earth is too big they consider it and let each other guard the North and South tribe. They will guide it by half and so on.
Luna fought thousands of thousands of bad beings just to guard and save the land and so for Anox.
Anox guarded the South Tribe steadily. Space creature is afraid to her. Anox can't see any light in South Tribe because the sun cant set there. Therefore, she wants to visit her sister Luna to North Tribe so she can see light upon the travel.
Meanwhile, while Anox is halfway through her destination. She sensed an evil being going to her guarded tribe.
