Our skyblock world on our server.

You have mysteriously awaken from a life you cannot remember. You have found yourself in some sort of afterlife, be it heaven, purgatory, or hell itself. A land made entirely out of diamond ore.

Remembering nothing of your pastlife, you decide that you must venture and explore this captivating world.

You are allowed to mine if you can. Do whatever it takes to get of this strange ring island. By ring island, I mean that you are isolated by the void itself from the rest of the land of Elai.

Godspeed.

Feel free to email me concerning any questions that may arise in your adventures.

My Solution to the SkyBlock 2.1 Hardcore challenge

Has a house and tree/melon/pumpkin/wheat/animal/sugar cane/cactus/mushroom/monster farm.

Everything done with Minecraft 1.2.5

If you start the map, you should head to the animal farm and catch the pig again, there is one that always gets out of the little cage.
