# World

The world is extended by a further 64 blocks underground, & Ancient City generation height is adjusted for this.

Oceans are made slightly deeper to account for the world depth extension.

Caves at this level are generally slightly larger & more windy.

The Overworld is made greener & brighter towards older Minecraft versions.

#### Rivers

Rivers can now have trees generate alongside them.

#### **Clearings**

Clearings generate in most forest biomes. They are characterized by a lack of trees and an increase in grass density.
