The Crown of the Crystal Rose
The Corruption is a very poorly documented entity. At the very beginning of the worlds creation, the Corruption was said to have existed. The Corruption represents hatred and death. In its physical form, Corruption is commonly depicted as a black mass of fibers and slime, similar to fungus.
While not much is known about the Corruption it is widely discussed and talked about. For the most part, the Corruption is sealed away but it can break loose occasionally and wreak havoc on the surrounding area.
Normal people and living objects will die upon contact with the Corruption. However, those with the Blood of a Hero can withstand the Corruption's death touch.
