When the Elder Gods had first created all of the 6 prominent realms by seperating the conciousness of the 'One Being', they had appointed protector Gods to ensure that the denizens of the realm live hamoniously. The Deities, Aramus, the God of Discipline and Tzeentch, the God of Change were appointed as the protector Gods of the now known Orderealm and Chaosrealm respectively. The people of these realms were no different from the people from the other realms untill the day 'The Tempest' was unleashed.
Tzeentch, the God of Change, due to his gift to tranform and manipulate ruinous energies was tasked by the Eldar Gods to contain the negative energies released by the One Being. A considerable portion of this energy had led to the creation of the Netherealm, whose essences were so corrupt, that even the Elder Gods did not know the full extent of the realm's corruption.Thus in order to prevent the creation of such realms, Tzeentch burdened the remaining portions of the energy. However with the passing of millennia, the burden of Tzeentch only grew, as the evil deeds done by the denizens of the realms contributed to the runious energies. Unable to bear the burden any longer, Tzeentch approached the Elder Gods, requesting them to relieve or atleast share his burden. But his pleas were heard only by deaf ears, as the Eldar Gods refused his request. As time passed, the ruinous energies got imbued in the God's very being and no longer being able to contain the energy, his essences shattered and spread across the lands of the now known Chaosrealm, like an epidemic, corrupting and severely mutating the people and lands with his 'chaotic' powers. The release of such immense negativity created a massive imbalance in the formations of the realms. Aramus, the God of discipline, realised the only way to protect his realm was to restore the balance by countering the negativity by releasing his own essences. The God of discipline dematerialised and his essences spread over the lands of the now known Orderealm, succesfully restoring the balance to the realms. This event went down in history as 'The unleashing of the Tempest' which led to the creation of Orderealm and Chaosrealm. The Chaosrealm became a world where its inhabitants practiced chaos as their religion, living in absolute anarchy. The Orderealm transformed into a realm that was the polar opposite of Chaosrealm, where law,order,structure and discipline prevailed. The two realms had remained without protector Gods,ever since.
