Stone of Gelel

The Stone of Gelel is a source of life energy contained in a mineral seen in Naruto the Movie 2: Legend of the Stone of Gelel. It was first discovered long ago as a vein of ore by Temujin's ancestors. Only the royal blood of his clan could forge stones from the ore, a process performed with flesh and blood of the body. These same forgers were also the only one's capable of destroying the stones.

The entire deposit of Gelel is said to be capable of destroying half a continent. For this reason a long and costly war was fought over it, resulting in the ore being sealed away by Temujin's ancestors. In the present day, only Kahiko knows the location of the Gelel vein, and he and his followers protect its secret.

Years after its sealing, Haido found some remnants of the stone by destroying Temujin's village. Later, he also found the Book of Gelel, which allowed him to learn how to control the power of the crystal. Haido wanted to use the Stone of Gelel to rule the world. To stop him, Temujin, who carried the royal blood of his clan, destroyed the stone and the entire vein of Gelel.
