Deep within Nekhuran's Harmonysteel Heartlands, the tainted core has corrupted the once pristine ecosystem. Anzu, a malevolent entity born from this corruption, spawns its twisted brood - Venomspitters, venomous creatures that plague the land. The heartstone at the center of the Heartlands, drawing dark forces from across Aetheran Odyssey, serves as a conduit for Anzu's power, making the Venomspitters ever more dangerous and resilient. It is said that the ancient Steelforged Cathedral, a testament to the region's terraforming prowess, holds a relic that may help banish the brood and restore balance to the Heartlands.
