In Minecraft, the sky is the limit. You can go anywhere, do anything, and be anything. But the world is more than just a sandbox. There are places, and they are filled with things that can be found only in the world. These places are called locations, and they have their own atmosphere, story, and details. 

For example, you may find yourself on a small, flat island. Or on a huge, flat island, full of creatures, monsters, and other players. Or on a mountain, or on a deep sea, or on a sky island. And in each of these places, you can find things that can be found only in that place.
