Fountain Pen Imprint Evidence

Fountain Pen Imprint Evidence first appears in The Lost Metal as a subtle forensic clue, where accidental ink transfer from overlying writing reveals hidden numbers 7-13 on an envelope. This technique marks a shift in the Mistborn saga toward more modern investigative methods, blending traditional Allomantic detection with mundane evidence gathering. The smudged imprint serves as a bridge between the series' earlier magical focus and its later emphasis on technological and procedural sophistication in crime-solving.
