Floating Islands

About
The Floating Islands biome is composed of small landmasses floating at high altitudes above the main landmass, west of the Spaceship Wreckage, just before The Chasm. The only way to reach the islands is by constructing a tower from Concrete Walls or a more durable material. Dirt and Wood towers are very likely to collapse under their own weight.

The islands are separated by significant distances so great care should be taken when traversing this biome, as falling off can result in death. A series of bridges can be built to ease movement.

In order to reach the Skylands, you need to defeat the Firefly Queen (See below) and use the Jetpack in order to fly high enough. The Skylands are the highest you can go in the game.

Floating Islands are one source of Gas Rock and Lightweight Rock. Gas Rock is needed for crafting the Rocket Tank for the spaceship used to escape the planet.

Islands are an interesting place for a base. If build correctly, only airborne monsters will attack it, making the defending somewhat easier. It is worth remembering that ground monsters will accumulate underneath the base during night time.

The Firefly Queen Island
This is the area where you fight the Firefly Queen. It's the highest island you can reach with Walls and knockback from weapons.
