The second Minecraft update is rd-131655. This is the first update with visual representation, and is regarded as the update that added grass blocks, stone, air, and world generation. Looking at these additions, I decided to add a new biome with new grass and stone variants as well as a new form of shadowstone to make it a little easier to obtain. This new shadowstone ore will be very common, but only in the new biome. This biome will be the basis of this dark era of mods that I make. The new stone can be used to make a set of tools which are better than stone. This would be nice if you get lucky and spawn in this biome. The biome also includes a new type of grass plant which will drop seeds for a new crop. This can be used to make a better type of bread. Each addition also has a detailed description in the MBB Guide item inside the game.
