In the series, the only Djinn seen originates from Taranushi's Chalice, an artifact made two million years ago by Goblins that has been the source of many battles between magical and non-magical creatures alike for thousands of centuries. When the chalice is filled to the point that the water runs over the edges, an evil Djinn will be released. The only way to recapture the Djinn is to use an incantation that was lost, according to Lao Shi, more than a century ago. In "The Talented Mr. Long", the chalice is mistaken for a trophy and put up as a prize for the school talent show.
