Pendant of Virtue

The Pendants of Virtue appear in A Link to the Past and are required in order to retrieve the Master Sword. Link must travel to three dungeons and collect each one before going to the Lost Woods to find the Master Sword. An ancient Hylian verse on the pedestal of the Master Sword about the pendants reads:

"The Hero's triumph on Cataclysm's Eve Wins three symbols of virtue. The Master Sword he will then retrieve, Keeping the Knights' line true."

Theory
Some have noted the similarities shared by the Pendants of Virtue, the Goddess Pearls and the Spiritual Stones. This could indicate a direct link between these artifacts, or equally it could simply be an example of the designers' desire to create a feeling of familiarity or a sense of a "shared legend" within the series.
