Truth lies in darkness.

A father. A silence.
Something left unanswered.

Dorian Hallow

His son is gone.
The questions remain.

He used to ask questions for a living.
Now he cannot stop.

What happened to Jacob?

A rural road through Greyhaven, with weathered houses and fields beneath an overcast sky.

GREYHAVEN / CONCEPT ARTWORK

Rural New York / 1976

Greyhaven.

Jacob Hallow’s death has an official explanation. His father has reasons to doubt it.

In Greyhaven, Dorian follows the traces his son left behind: through weathered homes, neglected roads, and conversations that stop when the questions become too specific.

The further he looks, the less the official account explains.

Look closer

Follow the trace.
Question the pattern.

Examine what was left behind. Compare records, objects and memories. A detail dismissed in one account may be the thread that connects another.

Listen for voices beneath the noise. Interpret the signs. What you find is evidence; what it means is still a question.

Memory / Ritual / Choice

The dead leave more
than remains.

Dorian’s search brings him into contact with spirits of the dead—and of those who were never born. Their memories hold stories of loss, hatred and revenge that never found an end.

Recover what remains of each story. Choose a ritual in response: help a spirit find resolution, destroy it, or walk away.

These choices do not change where the story leads. The world offers no reward for compassion and no punishment for cruelty.

Your choices reveal more about you than the world you leave behind.
