Introduction
What happens on Mars, you might ask? Are there really martians? Well, in real life, probably not, but this is Minecraft! These extraterrestrial beings are called the Amarians. Amarians do only four things in their daily life: Work, feed, eat, sleep. "Feed what?" you may ask, since they don't seem to have any pets. The Amarians must feed the Ykojinum (Yi-kawj-in-um) worm, a dangerous creature that, if not kept under control, could eliminate the entire Amarian civilization in a mere couple of seconds. The only think the worm eats is Earth cows, so the Amarians steal the cows and feed them to him. Any cows left over are killed and given to the alien citizens, or they are left alive and given to Amarians to power their homes.
Amarian Droids
"But how are the ships powered?" you might also ask. Well, the natives of the planet use droids to dig up lava from under the red planet's crust. The droids then give their capsules full of lava to the deposit station. The lava is then turned into a liquid called "Reekonium fluid", which are then poured into the ships' fuel tanks.
Amarian Homes
Amarian houses are very simple, as you can see in the images. They don't understand the concept of fancy houses that humans have. All they know is to build shelter, without fancy decorations. As you can also see, most Amarian homes are very high up, "So how do they get in?" Well, they use specially-crafted pads that shoot them up a couple of meters so they can get to their house safely.
The Mothership
The mothership is about 3x the size of a normal ship, and only the two leaders are allowed inside. Inside the craft, there is a Bovine Stabilization Room, which is where the cows are stored when they are abducted. When there are leftover cows, they are strapped down onto a Dismemberment Table, where they are killed and given to the regular Amarians. The mothership is also the only ship that has a defensive mechanism. If the fleet is under attack, they go behind the Mothership, while it shoots the attackers.

And that's pretty much it. I'm not good with conclusions.
