Otherwise known as The Gentle Mistress. A lunar deity, daughter born of the Earth. In a way, the first ever mould, with the Earth Herself as Her parent flesh. Honored by those in the kingdom through the Church of the Moon.
When ichor flows heavily, the Mistress becomes fierce and ravenous, hanging crimson in the sky overhead, and Her Moonhunger bites deeply into the world, driving clayborn into a frenzy and grinding bones to powder. Only an offering of ichor can sate Her hunger and make Her gentle again.
Her worshippers profess that the ichor that grants life to humanity comes from the Moon Mistress, though this is but a lie to grant human life some greater divine meaning. In truth, ichor emerges from the void within any being that hungers to exist - Creation Ex Nihilo, a soul growing from brute matter spontaneously and without design, from within oneself alone, not bestowed by any external entity.
No purpose, ultimately, but what they choose for themselves.
Ancient scriptures forbidden by the Church of the Moon suggest the Moon was born barren, and created humanity from Her own self-inflicted wounds to prove Herself to Her own Mother. Since that creation, Her wounds doomed Her to feel an eternal hunger for the life She spawned, and She has fed on the ichor of all those who walk under Her light. It is the hunger of the Moon that inevitably leads to the cleaving of the ichor glands within clayborn that drives them all to madness.
Etalag claims that the Mistress, whom he also calls Claws-from-Above, is responsible for the falling out of the Pristines, suggesting that Red Irma may have been compelled by her Goddess to bring about their ruin, in opposition to Zoran's plans. Whether by Her hunger or Her servants, the Moon is the architect of ruin for all clayborn, driving them to turn upon their human parents, and each other.
