The Underground Corruption is a Hardmode Biome. It is the underground version of the surface-level Corruption, and is initially created at and below the cavern layer once the Wall of Flesh is defeated. It operates similarly to surface Hardmode Corruption, being comprised of Ebonstone and Ebonsand, though it spawns different enemies.
Underground Corruption spreads just like surface Corruption, and similarly can not spread through Hallow. Additionally, small pockets of Underground Corruption can be created through the breaking of Demon Altars, which can convert a single random stone block in the world into Ebonstone upon their destruction.
Note: Most characteristics of surface Corruption also apply to the Underground Corruption. See The Corruption.
