Kaiu Roka

Travel
Carpenter Pass is the largest passage through Yugure Yama, and thus the easiest way to move troops across the mountains. Any soldiers travelling to the Kaiu Kabe have to pass through here, and the road is freaquently travelled by those who wish to test themselves against the minions of Fu Leng.

Defense
The road is well maintained as the Crab understand the need for open supply routes. Many traders and merchants set up along the road, but anyone who does must pay the Yasuki. Most of the traders are Yasuki anyway.
