This is fantastic, I love the lore around the Ogre-fication of people, it follows the setting pattern of Goblins being cursed people, and spreads in a very thematic way. Also, what Murky Borgy GM doesn’t want to give their players cursed treasure for their effort of slaying the beasty? The cycle sustains itself, though Ogres keep themselves fat and few between. In essence a great mid-boss for your adventure!
