Private: Sphere Enter at your own risk

By Dominik Mikulaschek

In **Private Sphere: Enter at Your Own Risk**, Mara Stein moves into an exclusive apartment building that promises safety, privacy, and complete discretion. From the outside, it looks like a dream: polished stone floors, elegant lighting, controlled access, silent hallways, and a concierge who seems to know everything before anyone says a word.

He knows when she breaks routine. He knows more than he should. As Mara begins to hear strange sounds in the ventilation system and notices details no one can explain, the building transforms from a luxury residence into a trap. The silence in the corridors becomes threatening. The technology becomes invasive. Even the comfort of her apar
