This is SkyPixel, similar to that of Skyblock in Minecraft. However, this one has a bit more depth to it, as it's Terraria. It pits you forth into a strange new land, where there is nothing save for the underworld, and a dungeon and... a single "Pixel" shape of a starting point. A thread will be created on TerrariaOnline.com forums to express all the challenges I have set for the map, as this description already isn't brief.
Please Note: The admins here at curseforge are no longer approving of my files. I will be abandoning their system in favor of mediafire links on the thread.
