Septerra Core: Legacy of the Creator - PC Games

You play as Maya, a young woman at the center of a power struggle to control her world. A fabulous, multilayered planet with a gigantic computer at the center, the planet was designed by an ancient creator. The Creator's plan works in such a way that once every century, the continental layers align so that light can reach the planet's core, powering up the computer and making its secrets accessible to anyone possessing the right keys.

Unfortunately for Maya and her friends, a Chosen Lord named Doskias has decided to hurry things along, and is prepared to destroy the planet if it means he can activate the Creator's computer 40 years early.

Recent role-playing games have a tendency to combine a fantasy quest and combat sensibility--including swords, spells, and, above all, healing--with what is otherwise a science fiction concept. Septerra Core is no exception. However, the layered setting of the Creator's world is vigorously thought out and beautifully drawn, putting this particular genre hybrid in a class above most of its competitors. --Alyx Dellamonica

Amazon.com Product Description
You are Maya, a junk scavenger, surviving on refuse dumped from above. Yours is a world of layers, in which continents orbit at different elevations around the planet. Those at the top, the Chosen, consume massive amounts of energy and dump their waste down to the layers below. Now, they have begun a descent to the Core, a living computer, in search of the Gift of the Creator, fabled to bestow great power. 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.
