The Black Mother sect of Gloombringer predominantly a manifestation venerated as a core part of the Nurthling faith of Shadren. The Black Mother is able to grow anything in the dark, and helps to provide Sustenance and for communities and Nurth children. She teaches them strict observance of Nurth community norms and practices for the faith. Those that fail are “given over to the patch”. The Black Mother is she who turns the foul into fair, waste into produce, the broken are made well – all within the context of what these terms mean to the Nurth.
A Mother’s Patch is a patch of fungus sacred to the Nurth community and imbued with the power to quickly process waste, sacrifices, and victims into nourishing fungus. The patch begins as an consecrated altar of the Black Mother – upon it are heaped the offal and waste of the commnity, and a sacrifice is made. It is from this patch that the “Black Mother’s Sourlings” – shrieker guardians, black slimes, green slimes, and death fungus’ – are brought forth. When a priest of the Black Mother dies, their holy presence and power are given over to the Mother’s Patch.
Guardian Shrieker Shared with Orrish: The Nurth have given over the Death Shriek Ritual to make the Shrieker to the Orrish through the Shadren faith of the Black Mother, but have kept the other creatures they Conjure from their patch a secret – these are the guardians of their communities. This is a fungus that looks a lot like a sponge. A potion of consecrated blood – unholy elixir, and excrement and waste cover it and within 24 hours a mushroom like “creature” will sprout, getting larger over the next few days. Within its caps are tubes and holes – those not of Nurth odor (or the odor of the grower(s) – who must remain close for a few hours) will set off its bellows like a shriek. The larger it grows, the farther its detection.
