How a Threshold Obscura story is made

Documents, geography, testimony. Identify the source and distinguish a reported claim from an established fact.

A real landscape gives the story its grounding. The unanswered questions create room to imagine.

Fiction gives the uncertainty a voice, a character, and a consequence. The boundary stays visible.
