The Expedition Arrives

An Ancient Site

Recognition in Stone
Their excavation reveals enormous, weather-worn blocks that match the masonry in Peaslee’s recurring dreams.
The Black Basalt Block

A Warning Sign
An Unusual Find
Peaslee discovers a square-cut basalt block unlike the other fragments and recognises its connection to the feared elder ruins.
Fear Reasserted
He tries to dismiss his reaction as superstition, but the discovery intensifies his dread of the northeast terrain.
The Buried Corridor

The City Beneath the Sand
A Hidden Entrance
A windless desert walk leads Peaslee to a buried structure and a cool draft rising through its rubble.
Familiar Ruins
He descends into the corridors, finding that their layout corresponds with the scenes he has dreamed for decades.

Evidence Lost
A Terrifying Flight
A strange wind and whistling sounds drive Peaslee through the collapsing ruins and back into the desert.
