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.
