Plot: You (and your friends, if you decided to do this with a group) were sent to the Last Shard via a Transmatter Array. You and all that were involved knew that it was a one way trip.
Your people's homeworld was blown into many pieces by a weapon made by a madman. You and a select few scientists escaped in a space ship outfitted with an emergency transmatter array.
After weeks of searching amongst the world bits, you found a piece that still had atmosphere, even though it was rapidly getting colder, and you would constantly need to wear some sort of protective gear.
You knew that it would not have atmosphere for long, but it was long enough to gather the resources needed to make a more permanent place, with an airlock and an air supply.
If you succeeded, the remainder of humanity would join you, and rebuild the human race.

Will you be able to rise from the ashes of destruction?

This is my first adventure map, and my first finished map.
It is not amazing, nor is it meant to be.
It is meant to be a fun challenge to race against time, either with friends or forever alone.

Challenges:

#1:Complete as many of the Minecraft achievements as you possibly can.
#2: Find the pocket-cavern under the water.
#3: Mine obsidian and make a Nether Portal.
#4: Find and assemble the End Portal.
#5: Make a home of stone brick, with a sticky piston door.
#6: complete 2-5 within a Minecraft fortnight.

Good luck, and Godspeed, soldier.
