In "The Canterbury Tales", how many pilgrims does the narrator meet at the Tabard Inn?

In the General Prologue, some 30 pilgrims are introduced. According to the Prologue, Chaucer's intention was to write four stories from the perspective of each pilgrim, two each on the way to and from their ultimate destination, St. Thomas Becket's shrine (making for a total of about 120 stories). Although perhaps incomplete, "The Canterbury Tales" is revered as one of the most important works in English literature.
