Saving Scout Makha

The tracks lead south from Makha's equipment, appearing to cross the Path of Glory. The roughness of the shallow ruts suggests that Makha's captors were in a hurry to move her to the next destination, but why? Was someone waiting there for her, perhaps Warboss Nekrogg, the leader named in the orders you found further north? The shield and the tracks raise more questions than they solve, but it seems certain that where you find Scout Makha, you're likely to find Warboss Nekrogg too.
