An artifact Found by Rafe in Luke's room. Possibly the key linked to the Kaziri Mr. Birch discussed.
The Kaziri was mentioned by Mr. Birch when conspiring with ex-mayor Nicky in the "Pilot". It is apparently buried, but neither Mr. Birch or Nicky seem to know where. Nicky expresses a wish to empty the town so they can resume the search for it, using a "backup plan" that Birch has qualms about. Birch expresses disappointment with the fact that Luke McCawley is dead, mentioning that Luke hid the key somewhere. Later, Rafe McCawley finds a golden artifact hidden in his son's room that may be the key.
