The Northern Way was the road that connected Northern Watch (P4) to the Castle of the Faithful Bride (P5). Rarely used by any except the Isawa, this narrow road was driven across Mori Isawa's border and along the northern mountains so that the residents of those two holdings would not be required to circle around the Mori Isawa to visit the other. This had had the additional benefit of providing a far more direct route from Kyuden Isawa to Pale Oak Castle.
