This map was inspired by two old maps: the original Skyblock by NOOBCREW (Minecraft version 1.0 - 2011) and Infinichest (Minecraft version 1.8 - 2014).
You will start on a single Shulker box, suspended in the void. The box contains a tree of many other boxes, which will eventually yield to you all of the resources you require to thrive in a Skyblock environment.
