The story

Leo Vasquez came to the bottom of the world chasing a flaw in a satellite image, a smudge of ice that refuses to behave, in a place his dead mother spent her life mapping. Maya has lived on the ice her whole life, and she knows better than anyone what it does to people who don't respect it.

When the ground opens beneath them, the two of them fall into something that was never meant to be found, proof that the most closed-off place on Earth has been kept that way on purpose, and that the people who sealed it knew exactly what they were hiding.

Now the truth is climbing toward the surface with them. And far above, the men who have spent decades keeping it buried have realised the ice has finally let someone in.

Some discoveries don't rewrite history.
They rewrite where we came from.

The record

In 1959, twelve nations signed the Antarctic Treaty. It locked down an entire continent: no military presence, no resource extraction, no permanent civilian population. It still holds today.

The official record says it was for peace.

The Last Latitude asks what else it might have been for.

FIELD RECORD 01: THE LINE RECOVERED. ORIGIN UNVERIFIED.
Aerial Antarctic ice field with a hand-marked rectangular frame and label 14.
FIELD RECORD 02: THE SIGNAL ACTIVE.
Aerial view of crevassed Antarctic ice with a hand-marked frame and label 491.
FIELD RECORD 03: THE DOOR SEALED.
Snow passage between ice walls with a rectangular opening marked 375.
