After destroying the guardian Gorl, they find the Topaz and continue to the Lake of Tears, accompanied by Jasmine after she is encouraged by the spirit of her now-deceased mother.

Eventually, after discovering the existence of a resistance against the Shadow Lord, they reach the Lake and persuade the gem's guardian, the monster Soldeen, to give it to them.

With the help of Doom, who also competed, and his friend Dain, who was disguised as a server, they manage to escape and reach the Shifting Sands, where they obtain the fourth gem, the Lapis Lazuli, from the living Hive.

They encounter a race of sentient animals called the Kin, and with their help, travel to Dread Mountain, pursued by the Shadow Lord's elite soldiers, the Carn Squad.

Lief also discovers that his parents have been taken captive by Fallow, the Shadow Lord's advisor, but his friends persuade him that the only way to save them is to complete the quest.

The Shadow Lord revives Thaegan again, and she attempts to defeat them with their worst fears, but they triumph over her once more and leave her to destroy herself along with all but one of her remaining children, Ichabod.

After this, pursued by both the Carn Squad and a pyrokinetic sorcerer, Oacus, they rescue Dain and find Tora, empty of its people after they broke a magical vow to shelter King Endon.

While Doom and Dain leave to return to the resistance, the trio journey to the Valley of the Lost and defeat the guardian, retrieving the last gem, the Diamond, after a scuffle with Oacus.

Doom and Dain arrive at the Valley, revealed to now be home to the people of Tora, and are eventually informed about the quest to restore the gems.

When they all swear loyalty to the new heir, Lief comes to believe that Dain is Endon's child, but he is quickly kidnapped by Ichabod and brought to Del.

Doom, who suffered a head injury in the capture, remembers his past, including that he is Jasmine's long-lost father, before they are rescued by Lief and the Kin.

It was directed by Mitsuru Hongō, designed by Hiroyuki Nishimura and Junya Ishigaki, and written by Oketani Arawa, Reiko Yoshida, and Natsuko Takahashi.
