Vivre Cards were drawn to one another.
Austin naturally knew that.
A "sub-card" torn from a Vivre Card would drift faintly toward the "main card," and the burning of the Vivre Card also indicated its owner's vitality.
It was worth mentioning that no matter how many sub-cards were torn off, there was only one main card. Even if it was torn down to a tiny scrap, the main card remained the main card and would not be drawn toward the others instead.

There had been entertainment, and he had saved
