Welcome to Septerra...

On the Outer Shell layer above, the ancient society of the Chosen live an extravagant lifestyle, consuming mass amounts of energy and dumping their waste down onto the layers below.

But things are not what they seem. The Chosen believe that Septerra was created in the ancient past by a mysterious being from the heavens. The world is a clockwork, built for some unknown purpose to work in the way it does. They have discovered artifacts and clues which lead them to believe that the answer lies in the depths of the Core, around which all the other layers orbit. It is this Legacy that calls them from their self-imposed exile, to return to the lower levels.

Now, as they begin their journey, they find that they cannot travel even one level down without artificial aid. Their bones have become brittle in the higher altitudes, their muscles stringy and weak in the lower gravity of the upper shell. But journey to the Core they must, for they believe it is their birthright to unlock the secret of the Legacy, and know the face of their Creator.

It is into these events that you are drawn. You take the role of a Junk Scavenger from World Shell two, directly below the Chosens' layer. Here you make your living, sifting through the trash from above to find useful items to sell. As the Chosen and their Technopapist regime begin their descent to the core, war looms over the land. The many nations of the lower levels, including your own, are threatened by the exodus, and fear the destruction to come. At first you stand in the way of the Chosen, fighting to slow their march to the Core, and protect your homeland. But it is you who will ultimately discover Septerra's true nature, as you journey out of the familiar surroundings of your home country, and come face to face with the Legacy...

At the Core, you will discover a planet-sized Bio-Computer, which holds the answer to the Creator's Riddle. You will learn that Septerra is a giant puzzle piece, waiting to be locked into the universe around it, as soon as its inhabitants solve the Legacy. If you fail, the world is certainly doomed. If you succeed, and solve the puzzle - it may well destroy you, and those you love ... Certain continents on the lower layers can be moved to the Outer Shell, where they will snap into place. If the correct ones are raised, an ancient symbol will be created across the face of the planet, and the Legacy will unfold. But is it the right thing to do? The moving of whole continents will cause catastrophe on a scale of which has never been imagined...

Against a backdrop of political intrigue and savage war, you will journey across the various worlds, encountering dear friends and wicked enemies. Travel to the core and unlock its secret. Face the war machine of the TechnoPapacy, and bring it to its knees.
