LIVING UNDER THE GROUND
In an inhospitable world, without days or nights, in a barely breathable atmosphere lacking oxygen, humanity had no choice but to take refuge underground. After long periods on the brink of extinction, they managed to overcome adversity through new techniques and great advances in tunnel excavation.
Finally, they created a connected underground world, although living outside the influence of the sun that they previously knew. To free themselves from this disconnection, they devised a device called "THE CUBE", which allowed them to enter dream worlds and escape, even momentarily, from the underground shadows. This device became his bridge to the light, a window to the memories of a sun that now only exists in his dreams.
