|Inhabitants||Various Departed Souls|
At some point in time, the Departed Realm came into existence as one of many realms parallel to Ninjago. All of its deceased -save for the wicked and cursed, and disgraced warriors unable to come to terms with their death- would have their souls sent to the realm upon death, where they would rest in eternal peace unless disturbed.
The Last Voyage (Flashback)
Samukai, desiring an inventor to manufacture weapons of war for the Skulkin, used Resurrectea to revive Dr. Julien, bringing his soul from the Departed Realm and returning it back to his body in Ninjago.
Attempting to wield all four Golden Weapons at once, Samukai was quickly overwhelmed by the power and disintegrated in the attempt. With his form in the Underworld destroyed, Samukai's lost soul was left to drift to the Departed Realm instead.
Having recently created the Mega Weapon, Garmadon attempted to figure out its abilities and in the process accidentally wished for Captain Soto and his crew of Pirates to come back to life. Drawing upon Garmadon's power and energy, the Mega Weapon brought back the souls of Captain Soto, No-Eyed Pete, the First Mate, and the rest of the crew from the Departed Realm. However, one of the resurrected souls, attempting to wrest the Mega Weapon from Garmadon's hands, would be killed by the overwhelming power and sent back to the Departed Realm once again.
Sometime afterwards, Dr. Julien would pass away once more due to old age, returning to the Departed Realm.
Seeking to reunite with Dilara, Nadakhan used one of his infinite wishes to bring her soul back from the Departed Realm, placing it inside of Nya's body. Later, when the Djinn was struck with the venom of the Tiger Widow, his power faded, causing Dilara to be sent back to the Departed Realm. After Nya was killed by the Tiger Widow venom, Jay used his last wish to reverse all events that had transpired since their escape from the hospital, thus erasing Nya's death and returning her soul from the Departed Realm.
Later, following the return of the Djinn Blade to Djinjago, its apparent destruction alongside its realm of origin would release the souls of Khanjikhan's predecessors and their enemies, sending them to rest in the Departed Realm instead.
On the Day of the Departed, Yang used the catalyzed magic of the Yin-Yang Eclipse to enhance the Yin Blade, tricking Cole into using its abilities to cut a rift from the Departed Realm to Ninjago. Using the Yin Blade's magic, Yang was able to bring back the souls of Samukai, Kozu, Cryptor, Chen, Morro, Eyezor, Zugu, four Stone Scouts, two Stone Swordsmen and multiple Nindroids from the Departed Realm, placing their spirits in statues modeled after their original bodies.
With the Yin Blade's magic only being able to keep the souls in Ninjago with the power of the Yin-Yang Eclipse, Yang instructed the resurrected villains to use the Departed Blades to switch places with their enemies, sending them back to the Departed Realm instead once the eclipse ended. Despite the efforts of the resurrected souls, however, all were killed, with Morro in particular having instead made peace with himself and his former before letting his soul return unheeded to the Departed Realm.
