|“A medallion. It's like a compass. When the three holes match up, the medallion will reveal where the temple is hidden.”|
|— Dr. Julien|
The Medallion is the only way to find the Temple of Light.
Wu handed Dr. Julien the medallion and Julien claimed it was a compass to find the Temple of Light. Later, Jay started playing with it and spotting trees until he accidentally found where the Temple of Light was hidden.
