To the east of Twilight Bulwark, the Twilight Withering is a similar outpost on a shelf southeast of Freewind Post in Thousand Needles. It's here the Twilight's Hammer have summoned a monstrosity, an elemental infused with all four elements along with some Elementium. Known as Animus, this creature is absorbing two powerful elementals, Bound Fury and Bound Vortex. Using The Doomstone, when it has absorbed enough energy from them it will explode taking Thousand Needles with it.
