The 1870 Sighting

A Craft Without Explanation
The city looks upward
A dirigible crosses London under a clear sky, its skeletal pilot visible above the market crowds. The image is strange enough to become a lasting memory and a seed for later prophecy.
Mystery enters public life
The craft is seen by ordinary Londoners and by St. Ives. Its passage establishes that the city’s later events have a history older than the immediate criminal plots.
The Academy Tracks Its Return

Calculation and Rumor
Reports from afar
Reports place Birdlip’s dirigible over distant seas and then nearer to Britain. The Royal Academy uses its observations to predict a descent toward London.
Competing interpretations
Scientists see a failing machine, while Shiloh sees an apocalyptic sign. The same trajectory therefore generates both technical forecasts and religious expectation.
The Return and Departure

The Ghost Becomes Present
A landing witnessed
Birdlip’s dirigible descends in front of a vast crowd. Its pilot and the Homunculus become visible, but the arrival does not provide the Academy with a simple explanation.
One journey ends, another begins
The dirigible collapses after Birdlip and the Homunculus leave in the alien spacecraft. The city’s legendary sighting concludes as a material wreck, while the travelers carry the mystery onward.
