The Hallow

The Hallow is a new "anti-corruption" biome which has been introduced in 1.1. It can be created with Hallowed Seeds and will stop the Corruption from spreading. The biome has light blue grass and colored trees. It also has its own underground biome which might be where pearlstone is located. Biome name was taken from bandcamp page.

The Dryad will tell the player the percentage of Hallow and Corruption in the world, after the player has defeated the Wall of Flesh boss in the Underworld.

Unicorns and Pixies will spawn here.
