Silver Box of Ix Chel
The Silver Box of Ix Chel holds the power to summon the god Kukulkan, but it needs the Key of Chak Chel to unlock it.
It was created by the Mother Protector, who also created the Yaaxil to protect the Box from falling into the wrong hands. Its original resting place of the Silver Box was in the Cenote but it was moved in the early 1500s by a Jesuit missionary called Andres Lopez. He was tasked by Trinity to find and retrieve the box but Lopez realised the importance of the item. He had agreed with the Emperor of Paititi, the Sinchi Chiqa to take the box away from Paititi. Lopez took the artefact to the Mission of San Juan, having a special hiding place created to house it.
