Khanjikhan

Khanjikhan is Nadakhan's father and the ruler of Djinjago prior to its destruction.

History
At an unknown point in time, Khanjikhan married and became the Djinn King, and inherited the Djinn Blade as a result. Afterwards, he had a son, Nadakhan. However, when Nadakhan left Djinjago to become a pirate, this resulted in his son no longer being welcome back home.

Enkrypted
Upon his son's return to Djinjago alongside the Sky Pirates, Khanjikjan noted the poetic fittingness of his coincidental arrival. Upon being asked why the realm was collapsing, he explained that, due to The Preeminent's death, and because Djinjago was the Cursed Realm's sister realm, this resulted in the collapse of their home. He then proceeded to give the Djinn Blade to his son, making him the Djinn King, and stayed behind as the realm collapsed, presumably dying as a result.

The Way Back
As a result of Jay's wish erasing the events of the season, Khanjikhan would never give the Djinn Blade to his son in the first place, resulting in the artifact's destruction.
