|“My story begins long ago. A time before the long Winter. A time when the realm was still lush and green. A time. . . before I lost everything.”|
After Grimfax refused to help Vex, the latter wandered the wilderness struggling to survive. He witnessed a portal that spat out Zane, who had been banished by Aspheera. Stalking Zane, Vex would be intrigued by the latter's power and usage of his scepter when repelling an Ice Bird.
As Zane attempted to repair the Titan Mech, Vex attempted to steal his weapon but found he couldn't wield it. Having overheard, the risks of Zane prematurely interrupting the progression of his repairs, Vex pulled the mech's plug. This act erased Zane’s memories, as Vex took advantage of this by convincing him that Zane is the Ice Emperor and Vex is his trusted advisor.
With Zane’s help, they overthrow Grimfax and his Warriors and turned them into Blizzard Warriors with the use of his scepter. After that, Zane donned the Ice Emperor Armor and froze the Never-Realm in eternal winter.Following Zane's takeover, Grimfax was demoted to the leader of the Blizzard Warriors and was the only Warrior that was never corrupted, just turned into one and coerced into serving Zane and Vex.As the Ice Emperor, Zane used his powers and his Scepter to create the rest of the Blizzard Samurai in which the Sword Masters and the Archers were created out of Ice and Snow. He also created the Ice Dragon Boreal, which would obey his every command.
The self-exiled Vex returns to his village just in time for the choosing of Akita and her brother Kataru. Many were surprised to see "Vex the Formless," while he expresses sarcastic pleasure to see them, as he calls them out on banishing him. However, the village leader states he left of his own accord and Vex angrily brings up their mockery before he tells the Formlings that he found an Elemental Power greater than the abilities of the Formlings. He requests they submit to him or he'll bring an army to eradicate them, but the leader stands his ground and Vex retreats, promising them he'll back.With his offer refused, Vex persuaded Ice Emperor to attack the Formlings' Village by lying to him of the Formlings being war-loving people. After obtaining her form, Akita returned just in time to watch as The Ice Emperor and Vex proceeded to freeze the Village of the Formlings. Attempting to stop them, Akita was knocked aside by the ice dragon Boreal who attempted to make her share the same fate as her people but Akita's brother intervened but ended up presumably frozen too, leaving Akita and Kataru the only survivors.
With her people frozen, Akita would leave and go on to swear revenge against Vex and the Ice Emperor. Unbeknownst to her, Kataru had survived being frozen and was taken to the Castle of Ice by Boreal as a prize.
Shortly, after the Freezing of the Formling Village, Zane decided to annihilate the Yetis for unknown reasons. All of them were annihilated except for Krag.
As a result of the annihilation, Krag buried his friends and family in his cave where he isolated himself. Despite all of that, he still remains pretty friendly as he saved Cole and the fishermen from different avalanches. Cole later convinced Krag to join him and his friends in stopping the Ice Emperor and trying to find Zane, unaware of what happened to him.
- This event marks the second time where a Ninja is responsible for the death or near extinction of a race.
- It is unknown why the Yeti were attacked in the first place.
