About This Game

In a city where memories fade, the truth must be reconstructed.

Welcome to Cyl-Hestia , a city-state built around Cerulyn , a mysterious blue flame with exceptional properties.

As the authorities are prepared to do anything to maintain their power, you play as Silas , a memorialist working for the independent newspaper The Voice .

Your mission: to gather fragments of memories to reconstruct the events obscured by the regime... and rekindle the flame of truth.

Explore the districts of Cyl-Hestia and collect Memory Records , short testimonies entrusted by its inhabitants. Combine them to reconstruct Remembrances and Mnemosyne Visions , revealing events buried in the collective memory.

Every discovery fuels The Voice 's investigative work. With every published article, the world changes: surveillance intensifies, tensions arise and people become aware of what is happening.

Your progress has a significant narrative impact , gradually revealing the full extent of the manipulation at the heart of Cyl-Hestia.

You can interact with the environment via a sound hacking system.

Program punch cards to decipher encrypted records, unlock forgotten passages, or interact with ancient technological devices linked to the Flame.

In a world blending retro-futuristic science fiction , film noir atmosphere and mysticism , meet memorable characters, infiltrate the corridors of power, and explore the different levels of the city, from its forgotten slums to the sacred Spire tower.
