In Terraria, is it possible to completely reclaim a Corrupted area?

Well, what I tried to do was completely cleanse a Corruption area. I assumed it’s all about the grass, since that seems to be how the Corruption spreads, and other biomes (such as the Underground Jungle) work like that.

So, I bought a few stacks of Purification Powder and Sunflowers, and purified every bit of Corrupted grass I could find.

  • What new NPCs are available in 1.2?
  • How can I kill adorable animals?
  • What makes plants bloom?
  • How do I control which NPCs live where?
  • How do I progress past the initial tier of gear/crafting in Terraria?
  • How can I improve my chances to find Hearts (Life Crystals)?
  • It didn’t completely work, however. Slimes/Zombies now spawn, but so do Eaters of Souls, still — and the music hasn’t changed.

    Is there something else that has to be done to completely eradicate the Corruption? (I’ve already smashed every single Shadow Orb; I doubled checked using the World Viewer.)
