- New wood types
- New ores
- New basic enemies (in-dimension zombie, skeleton, creeper equivalents)
- New basic mobs
- New crops
- New food items (both from the game and entirely new ones)
!THE MOD IS CURRENTLY IN ALPHA, ONLY THESE LOCATIONS ARE PRESENT IN THE MOD!

How to open a dark fountain
To open a dark fountain, you first need to get a sharp item, iron or tougher (either a sword or a spear). Second, you need to craft a SOUL CAGE.
After crafting the soul cage, it will give you the "Concentrated" effect, when right clicking with it.
After concentrating, pick a spot to make your fountain in. When you do, right click on the spot with the previously mentioned sharp object, WHILE being concentrated.
A dark beam will appear on the chosen spot, which means everything was done correctly.
How to leave a dark world
To leave a dark world, you will need to mine for black shards (Bits of shadow crystals. They will later be accessible by beating secret bosses).
After collecting 6 Black shards, you will also need 2 iron blocks (and your SOUL CAGE). Using the three items, you will be able to craft a Home Beacon.

(Note: the recipe may change in later updates. If one time the recipe stops working, check this again)
After doing that, place down the Home Beacon, and right click it to open a light fountain (right clicking again closes it). After you've done that, you will need to concentrate, before right clicking it, and leaving the dark world.
