Vex's Crystal

Dark Ice is a corrupted type of ice used by the Ice Emperor, General Vex, and presumably the Blizzard Samurai.

The Never-Realm
Sorla tells the Ninja that the Ice in the Ice Emperor's Castle is corrupted then later warns them of General Vex who is out to get the Ninja using Dark Ice.

Inside the Ice Emperor's Castle, Vex is seen using Dark Ice to spy on the Ninja, so he tells the Ice Emperor of his findings. The Ice Emperor then demands Vex to send the Blizzard Samurai to destroy the Ninja and all who aid them.
