[Arcadian Empire]

Alas, the widgets chapter of the history of Rome was locked in a box by an ancient scribe, who lost the key and swore to tell no one where the box was until he found the key.

Decades later, he handed his grandson an iron key, and said that if the grandson returned at sunrise the next day, the location of the box would be revealed to him.

However, the grandson was killed, grasping the iron key, with the Latin inscription

parva excambium operariorum in perpetuum

written on his chest.

Just hours later, his grandfather was found killed, with the same Latin inscription

parva excambium operariorum in perpetuum

written on his chest as well.

[Colinsky]

parva excambium operariorum in perpetuum

"a small amount of compensation for workers in perpetuity," according to Google Translate.
