North March

The North March' as Jaller described to Takua on MNOLG: "The North March is an icy pass where Ta-Wahi meets Ko-Wahi, and is only accessable by zipline. Only members of the Ta-Koronan Guard have access to the Ta-Koro end of the zipline." Apart from that, the North March has never been mentioned in books or on BIONICLEstory.com.
