Estate of Hollow House

A Cosmic Horror Investigation Overlay for the Poker Run Engine™

The house was condemned forty years ago.

Every inspector who's been sent in since has come back with a shorter report and a longer silence.

The blueprints don't match what's inside.

Some rooms don't match the ones next to them.

And somewhere past the Below-Stairs, something has been waiting since before the house had a name.

They call it The Presence.

ENTER HOLLOW HOUSE

Estate of Hollow House is a solo cosmic-horror investigation overlay for the Poker Run Engine™.

Assemble a team of investigators. Push deeper into the house. Gather evidence, recover testimonies, uncover sealed rooms, and piece together the truth before the house decides you're part of the evidence.

Most teams don't file a final report.

You're going to try anyway.

ONE DECK. ONE HOUSE. THREE ENCOUNTERS.

Each investigation uses a standard 52-card deck.

Draw a card to determine what waits inside the next room.

• ♠ Manifestation — The house shows you something it shouldn't.
• ♥ Trapped Witness — Someone survived long enough to tell you something.
• ♦ Hidden Archive — The house has records. Some of them were never meant to be found.
• ♣ Sealed Room — There are places inside Hollow House that were sealed for a reason.

Face cards trigger unique events, including The Informant, The Medium, and The House Notices You.

Then make your checks using poker hands.

High Card. Pair. Two Pair. Three of a Kind. Straight.

Your cards determine whether the investigation succeeds — but every decision costs something.

PUSH DEEPER

Hollow House is divided into four Wings.

The Foyer The safest place to begin.

The Upper Wings Better evidence. Worse manifestations.

The Below-Stairs Mixed threats, rare discoveries, and a house beginning to fight back.

The Room That Isn't There High risk. High reward. And somewhere inside it is what you came looking for.

Your Case File determines how far you can go.

Your team determines how well you survive.

And the deeper you go, the more the House notices you.

The Presence cannot simply be confronted.

First, you must uncover what Hollow House has hidden.

You will need:

Only then can your Case File reach its final stage.

Only then can you face The Presence.

And when you do, you'll need to survive three final Checks.

The house has been waiting.
