Kantoo first appeared in flashback in A Hero Discovered, in which his creation of the Kyber Saber using Kyber crystals to form a blade was touched upon. Kantoo's weapon proved incredibly powerful, amplifying the Force abilities of the wielder, but he soon discovered that it had terrible destructive potential. In order to prevent its ill use, Kantu broke the blade into several component crystals and had other Jedi hide them on various planets across the galaxy. Many centuries later, Kantu's worst fears would be realize when Naare, a Sith acolyte acting on the orders of Emperor Palpatine, reassembled the Kyber Saber and attempted to use it to overthrow her master and take his place as ruler of the galaxy. Fortunately, the young Rowan Freemaker, a Force sensitive with a unique connection to the Kyber Saber Crystals, was able to defeat her and cast the Kyber Saber into a volcano, insuring that Master Kantoo's wish that it would not be used for evil would be fulfilled forever.
