Le Cadeaux des Ancients

From the introduction:

This adventure is designed to be played by a gamemaster and a single player, not the traditional party of adventurers. It could be adapted for more players, but at heart it is a simple, personal story and works best one-on-one.

The year is 1748 and the setting for this adventure is the city of Paris.
