Jennamite



Jennomite, also known as Creeping Crystal, is a mineral that grows at great speeds, usually fashioned into rings and placed over a person's finger. The mineral grows around the finger and over the body until it has encased the victim within. It is heavily implied by King Bumi that a person dies once encased completely, probably due to suffocation or inability to move.

In "The King of Omashu", King Bumi begins to encase Katara and Sokka with Jennomite in order to force Aang to complete his challenges. Once Aang succeeds, the king shatters the jennomite with his Earthbending. It is revealed in this episode, as well as in "Sozin's Comet, Part 2: The Old Masters", that Jennomite is in fact a type of rock candy. If Jennomite indeed reproduces itself when in contact with living tissue, it is unknown why it does not reproduce within a person's stomach.

Whether Jennomite is created artificially or found naturally is not known. In the series, it has not been seen outside the city of Omashu.
