Deep inside the icy caves of Okoto, the Protectors of Ice reside, guarding the masks of power. Kopaka's mask is the most well known mask. But there are others too, just waiting to be reunited with the Toas of Ice.
The Protectors themselves have a leader who guides them and provides the wisdom they need to fulfill their missions. This is that leader - Varkka, the Lord of the Ice Protectors.
