I basically threw Norse Mythology and Midieval culture in a blender with my own imagination, so excuse any inconsistencies from either side.
PLOT: 10,000 years ago, the world was erased from existence. The titans, revived and led by the traitorous god Loki, ravaged both Midguard and Asgard, decimating the human population, and managing to kill many of the gods as well before Loki's eventual death by the hands of Thor and Odin. On top of the earth destroying war between the titans and the gods, Loki's sons-Fenrir and Serpent, join in the fight as well, killing both Odin and thor, though they sequentially die themselves.
In the midst of this war, the servant of the demon god Ragnarok, Tälwark, managed to attain all of the required items to summon the great beast(Thor's hammer Mjonir, Odin's Eye and spear, and Loki's staff). Ragnarok, the great terror, began devouring world after world, pushing the entirety of the universe to extinction. However, the remaining Gods managed to draw on the power of the Universal tree Yggdrasil, creating the sealing box Pandora, locking away the demon after it had devoured seven of the nine worlds. However, they were unaware of the consequences that followed drawing on Yggdrasil's power.
In order to seal Ragnarok away, it's power had to be divided into it's seven purest forms so that it's soul was left too weak to break out of Pandora, the seven deadly sins of humanity. These seven forms, since they contained too much power to seal, were imbued(once more with Yggdrasil's power) into the surviving humans, but because of Yggdrasil's curse, humanity was given the burden on reincarnating the seven sins every generation, along with the fallen gods being reincarnated as well. In the present day, the tales of the war, Ragnarok's destruction, and Pandora's curse have been reduced to nothing but myth. However, there is one man, who goes by the name 'Prophet', who is-along with his ten 'disciples'-attempting to find Pandora, and all of the items to ressurect Ragnarok once again, which were scattered across the earth(with the exception of Odin's eye, which was inherited by Odin's reincarnation).
SETTING: A midieval, Knights and Wizards type setting for earth. There are seven large kingdoms, one for each continent on earth. Knights are the equivelant of 'ninja' in Naruto, and while Combat magic is pretty common among Knights, it's usually the responsibility of Mages to use healing/support magic. A Kingdom is ruled by three major figures(thought he king has the final word). The Wizard, who represents the Mage Population, the Paladin, who represents the Knights, and of course, the king that rules the civilian side, and basically everything else. I'll go into more detail later. As Yggrasil's destroyed worlds were rebuilt, the races of those worlds(Elves, Trolls, Leprachauns, fairies, dragons, cyclopses, etc.) returned as well, so other races besided humans and gods exist, just on other worlds.
The story will primarily take place in the kingdom of Baoill(bay-ole), the kingdom of the third continent.
