Modern Paganism identifies the Dark Goddess as an archetype, and there are many historical Goddesses who are often associated with that title.
I’m currently world building, and it is a world full of Goddesses who have titles rather than names. Of course there is a Dark Goddess.
She is the balm of darkness after the agony of too much light. She is the peace of oblivion, free to rest without scrutiny for a while. The paths to her are many, and they are strewn with bones and broken dreams. There is no pain she does not understand. There is no horror that she cannot witness. She is the comfort when all comfort is gone. She is the last, desperate breath, and the breath that comes after it.
Come to her in despair. Come to her on your knees when you can no longer stand or walk. Bring her the broken wreck of your body and the ruined tatters of your mind.
Her temples are the cairns of stones on battlefields where no one remembers any more what the fighting was supposed to be about. Her temples are the mass graves of the nameless dead. Worship her when the night is pitch dark. Honour her when there is no way forward and yet somehow, you must continue. Whisper to her the names of those you know you will never see again. In her embrace, no one is lost or insignificant.
She does not offer redemption or forgiveness. Sit with her for long enough and you might find out how to make those things for yourself.
