 What motivates Zarwell to take on the 'missions' he leads?
Zarwell moved among them, seldom taking part in the individual clashes, yet a moving force in the conflict . Zarwell was riding a shaggy pony outside a high wall surrounding the stricken metropolis. Zarwell was not the leader of the invaders, only a lesser figure in the rebellion. A WORK truck picked Zarwell up the next morning and he rode with a tech crew to the edge of the reclam area. When Zarwell arrived, six months before, the vitalized area already extended three hundred miles along the coast, and sixty miles inland. They were loaded with ore that would be smelted into metal for depleted Earth, or for other colonies short of minerals. Zarwell pulled his sun helmet lower, to better guard his hot, dry features.
