Deos vs. The Eternals

When Deos confronted his children, demanding to know why they have committed the sins they have, he was met with vast power targeting him. The Eternals' combined strength was greater than his own. If he were to win this fight, sacrifices will have to be made.

After trying desperately to find the cause of the corruption that now endangered the world that he, and his sons had made, he was contacted by the dragons. They told him of how dark beings were corrupting the different peoples, and driving them to sin. Only fear washed through Deos' mind, as the only beings "from beyond" other than himself were his seven children.
  He confronted them, and saw their twisted, sinful forms. He demanded to know why they did this, why they are destroying their own creation. They told Deos, they were not destroying their own creation, they were destroying Deos' creation. Deos replied saying how in planting this sin, and inflating it to this scale, they had compromised the stability of their world. He demanded that the Eternals undo their mistakes. Instead, they lashed out at Deos.
  They could not harm Deos, but their combined power made them nearly impervious to Deos' counter attacks, with Envy's total power rivaling that of Deos. However, the created cannot harm the creator. He could not bring himself to destroy his first creations, but without help, he'd be forced to. He made a temporary escape into the void where even his closest children don't go, as they fear its emptiness.
  There, Deos would split himself in two. Each half retained the same power of the original Deos. One half contained his love, his desire to create, his perfection. Though it still had his willingness to fight. The other half had his wrath, his rage, his fury. It knew no love, no art, no desire to create. In fact, it had quite the opposite. Its only desire was to destroy.
  The following fight shook that entire dimension in what the mortals called the "Storm of the Gods." The battle itself would last nearly five hundred years. Half a century of clashing entities, each of enough power to end a dimension on a whim.
  Eventually, Deos and his wrathful twin were able to subdue the seven Eternals. It became clear that Deos could not clean up his children's mess without them interfering. To ensure they do not do so, he cast them into the next realm. Immediately after, his wrathful twin lashed out at him. Deos was forced to do the same to the twin. He felt sorry for the Eternals. Not just for what they had become, not for what prompted it, but for placing that thing in the same plane of existence.
