Ora Dagger
Taken from Antarctica by one of the sailors from the HMS Beagle to a remote island in the South Pacific, it fell into the hands of a member of a cannibalistic tribe. He used the power of Ora Dagger and became the leader of the tribe, residing in a temple across Madubu Gorge. We can assume that his name was Puna since the temple was christened after that name.
Powers
The individual power of the Ora Dagger allows the bearer to summon beasts and manipulate electro-static particles in the atmosphere to create lightning. The bearer may also produce a energy barrier to repel gunshots and missiles.
Considering the elementalist beliefs of its creators, the Ora Dagger symbolizes the power of Air. It allows Puna to command lightning and summon creatures out of thin air.
When combined with the other crystal artefacts at the Meteorite Cavern, it will rapidly speed up the evolution of the bearer.
