Four Silver Fangblades

The Four Silver Fangblades are important Serpentine artifacts and weapons. They appear as silver daggers with ornate designs around the base of the blade and a round gem set at the end of the hilt. The gems and blades glow with a colored aura—green, red, blue, and grey—corresponding to the colors of the four main Serpentine tribes.

They are needed to summon the Great Devourer, which was said to consume all of Ninjago when awakened. The Fangblades were created from the Devourer's teeth, and are thus nearly indestrucible—only the magma of Torchfire Mountain is hot enough to destroy them.
