The idigam’s mere presence causes the natural world to rise up in revolt. Plants erupt into growth and overwhelm buildings in mere hours, while animals become ferocious and aggressive. Creatures of all kinds become incredibly fecund and fertile, often accompanied by murderous levels of territoriality and competitiveness. Each hour that the idigam is present in an area of radius equal to its Rank in miles, all stationary mechanical objects and artificial structures suffer one point of Structure damage as vines wrap them, mold blooms amidst their workings, and concrete shatters from rising roots. Animals are aggressive to all human beings, Uratha, and supernatural beings. Any attempts to influence them — including supernatural powers — suffer a penalty equal to the idigam’s Rank.
