Four private instruments
No one sees the whole truth.
Each phone becomes a different recovered instrument—revealing light, bearing, sound, or time that the others cannot read alone.
The Gate of False North
They found a sky below.
The last clear transmission ended at 11:46. The camp remained intact. The expedition did not.
The story before the door

The recovered file that begins the expedition. Gather 2–4 Keyholders in the same room before opening it.
A mystery made for the table.
A vanished expedition left behind four impossible instruments and a map that refuses north. Gather around one shared screen, claim a different instrument on each phone, and discover what happened beneath Sable Basin.
It starts with a question.
It ends with a story.
A cylinder stands in the dust.
It has no tracks leading to it, no maker’s mark, and something inside that knocks once when touched.
Every bearing tells a different truth.
Each Keyholder sees the expedition through a different instrument while the map rearranges what north is allowed to mean.
A sky waits below.
To find the vanished expedition, the table must decide which impossible account can still lead everyone home.
The Room is being prepared
