Second War against the Darkness

Second War against the Dakness is a conflict currently in the process of being fought between God and the Darkness. It started when the Darkness was released by Dean Winchester and Rowena through a spell, after the removal of the Mark of Cain.

History
God existed alongside his older sister, the Darkness. Despite his sister's disagreement, God created many worlds, in order to show her that there could exist other beings besides them, that could, in the end, turn out to be better than them. Refusing God's proposal each time, the Darkness destroyed all that he created.

Seeing her imprisonment as the only solution, God created four Archangels (Michael, Lucifer, Raphael, Gabriel) and barely succedeed in sealing her away by tricking her, the Mark of Cain serving as both lock and key.

Following the release of the Darkness, she automatically declared war to her brother and subsequently, to all of his creation. She started to torture and kill humans, in order to tempt God into revealing himself. Being unsuccessful, she captured God's favorite celestial, the fallen Archangel Lucifer, and started torturing him. He was later rescued by the Winchesters. Dean acted as a distraction, while Sam rescued the heavily damaged Archangel. However, the Darkness realized something was wrong and almost killed Sam, Lucifer and Donatello, before God intervened and saved them. Currently, they united forces and are preparing to wage full scale war against her.
