Regional Effects

Any flowing water within 50km of the aspect becomes thick and oily, ceasing to flow.

This thing appears to be a large silvery black Ammonite like shell, but peering into the end it's possible to see a human like face, much to large to belong to any normal person and with eyes like the darkest depths of the ocean, from the overlarge human mouth long barbed tendrils extend around a cruel beak.
