Dragon Eye II

The Dragon Eye II was the second Dragon Eye that was constructed by Hiccup Haddock after the original one was seemingly lost in the Volcano on Dragon's Edge. It appears in Dragons: Race to the Edge, starting in season 5. Hiccup was also inspired to build it because Viggo already possessed the original Eye after taking it from a volcano.

Eventually, the riders saw that in the wrong hands, the Dragon Eye could be used for evil and decided to destroy them both.
