The Great Peaks

==== "The Great Peaks are the largest mounts in the world. Touching to the sky, almost as high as the Floating Islands. If the corruption, crimson, or hallow ever enters these peaks, we will have the low ground." ==== The Great Peaks is a mini-biome that spawns near the beach on the dungeon side of the world. It is made mainly of stone, and is like a supermassive pyramid of stone. No blocks in a 10 block radius of it will be corrupted. It always reaches up to 5 blocks below the Floating Island spawn range. Going inside the mountain will lead the player to a shrine, and they will find the Mountain Shrine, where the Monk will be worshipping in. If there is a vacant house, the Monk will join the player and live in that house. The Monk will die if the biome gets corrupted, crimtame, or hallowed, therefore it is necessary to do this in pre-hardmode, before the Corruption, Crimson, or Hallow can destroy it. It is the only place Wyverns can spawn in in pre-hardmode, and when they spawn in pre-hardmode, they will only spawn after Skeletron and they will have 2000 / 4000 HP and 25 / 50 damage.

In Hardmode, Souls Of Height will now drop from enemies in the higher layers. Speaking of Enemies,
