Realm Crystal

The Realm Crystal was an ancient gem-like artifact created by the First Spinjitzu Master to leave the Realm of Oni and Dragons and find the perfect place to create his vision of a realm of balance, Kandrakar. 
It was capable of opening a portal to all of the realms, except the Departed Realm. 
Once kept in its creator's hidden tomb, the Realm Crystal was sheltered from anyone hoping to traverse realms for malicious intentions.
The N.I.N.J.A.S eventually found the Tomb and claimed the crystal, though it was promptly stolen by Morro to free The Preeminent. 
Before meeting his end, Morro gave the crystal to Wu, who had Cyrus Borg guard it in a stronghold in Hiroshi's Labyrinth. 
The crystal was later stolen by Nadakhan to free his crew who were stranded across the Realms of Creation, and it was accidentally shot and destroyed by Flintlocke. 
The artifact was restored when Jay made his last wish, undoing recent events.
The crystal remained in the labyrinth until it was relocated to the basement of Borg Tower.
