===The Hallow===
The Hallow is a candy-colored land of death. It appears after the end-of-the-world event that is Hardmode, and is the only terrain that blocks corruption other than man-made blocks. The Hallow spreads quickly if started, just like the corruption, but it won't overlap the Jungle and most terrain it converts into Hallowed versions of their basic terrain, just like Hardmode Corruption and Crimson. Strong blessed creatures, such as Unicorns and Pixies, dwell above and below ground. Whilst more photogenic, they are at least as dangerous as the foul monstrosities of the Crimson or Corruption. If you want to shoot rainbows and master magic, you'll spend a lot of time here.

Post-Golem, a constant danger becomes not hitting Prismatic Lacewings, lest a gigantic fey will appear to teach you a lesson.
