The laws of Altera are mystical and grotesque, at times defying the laws of physics and chemistry, yet in many ways resembling the real world. Here, a multitude of diverse creatures reside. The time and level of technological advancement in this world is far from modern standards and takes place in the conventional Middle period. However, in some areas technology typical of our time is used. In general, technology is rather primitive, and for the most part the inhabitants are skilled in crafts and manual labor.

Altera is not a planet, and its world is not flat. As new territories are explored, the world constantly expands. There exists a legend that there is indeed a boundary to the world, beyond which lies another mysterious and concealed world, dubbed the Outside, where beings with their own culture and world structure reside. However, no matter how hard travelers strive to reach the world's edge, it always seems to elude them.

However, it is possible to enter it. Passages to this world are corridors with many doors that can open in the most unexpected places, whether at the bottom of a lake or in your closet. But you are unlikely to be able to return to your own world.
