MEGACUBE.

No one saw MEGACUBE appear. One day it was simply there above the city: a black face against the clouds, too precise to be a mountain and too vast to be a building. Millions of segments remain dark until images and stories appear on them. The cube remembers every mark and shows it to everyone. They say someone once passed through it and emerged changed. They also say an unseen observer follows anyone who dares to climb.

At night, the hero leaps from the first platform. There is no staircase ahead: every foothold demands its own jump, and he must spot the next before taking off. Photographs, drawings and other people’s stories glow between the black segment faces. He climbs higher, yet the destination no longer feels like a summit. For a moment, one dark face seems to watch him. He turns; nothing has changed. The feeling of being watched remains.

Beyond the crest, the wall ends and the hero falls into a square shaft with no visible bottom. Images move in waves across its four walls, as though the cube has a pulse. Hands reach from cracks; they are trying to catch and stop him, not merely startle him. Voices arrive with them, felt through the skin rather than heard. When he listens, they fall silent; when he moves, they return. Somewhere beyond the flowing images, a motionless point keeps him in sight.

The tunnel ends in silence. Beneath white tiles and sterile light, the same segments the hero saw outside begin to show through. Corridors change behind him: the labyrinth has no fixed map and forms anew around whoever enters. Its creatures hunt with purpose, cutting off the way out. The voices under his skin grow clearer and seem to call him where he must not go. Yet the most frightening thing is not the chase. It is the presence of whoever watched from the wall and the tunnel.

The boundary between cube and city fractures, as if reality has lost its familiar shell. The hero steps onto a wet street but sees a second layer over it: segments, markers and another presence show through puddles and paving stones. This is ALPHA, not a new location but a change in how he sees the world. MEGACUBE was the first trial; he cannot unsee what it revealed. And if he can look through the surface of things, perhaps something beyond it can now look back. Did he leave alone?
