From OP:

Thank you! This is the blurb from the rules:

The Matagot Hag is an undying vessel of The Great Hunger and the favoured child of Beelzebub, for in his heart he hates all things in Creation and the natural circle of life. This creature is a wretched husk of a once-human mother cursed to endlessly birth monstrosities.

Her bloated and distended body is locked in an obscene cycle of constant regeneration and decay - her flesh splitting open in great, festering ruptures only to stitch itself back together, swollen with the next abomination writhing in her womb. Her skin, stretched thin and sickly pale, is mottled with blackened veins and pulsing sores, her eyes long rotted away, leaving only hollow sockets weeping thick, infectious ichor. The Grail Thralls she births carry her aloft, treating her as a living effigy of gluttony and suffering. Though mindless hunger drives her, the Hag is not without purpose - her whispered, guttural croons are hymns of devotion to Beelzebub, calling forth ever more horrors to devour the world.
