A pendant with a green stone
Pamela's Pendant was a magical necklace that Pamela Bousquet stored her powers within to keep her love spell on Qalmor intact. After her death, the Master had his minions steal her pendant for future use.
In 2001 on Samhain, the pendant activated when Pamela returned to the world of the living. Pamela started channeling her powers of invisibility and telepathy through it, but was unable to undo her love spell due to the Master's interference. He then destroyed the pendant to release Qalmor from the spell.
