David's response was to fire his lance at Wilkins.

Wilkins, however, had anticipated this and sprang out of the way. A beam of green ba light, pure godly essence, crackled out from the lance's mouth, striking the man who was standing behind Wilkins. It seared a hole through his chest and he fell to the ground, shuddering in death.

Wilkins rolled and came up firing. Golden light blazed from his Horusite lance, but it was a wild shot and missed its target, scorching the step at David's feet instead. David leapt back and took cover behind a column. McAllister joined him, firing as he went.

The Nephthysians started shooting from above, strafing the valley floor with purple beams. The paratroopers scattered, loosing off retaliatory shots. Wilkins's bogus Horusites also scattered. Shafts of light criss-crossed the valley at all angles, a cat's cradle of lethal, coruscating power. Men were shouting and screaming, their faces lit up by the rippling exchange of fire.

David took aim upward and shot at the origin points of the purple beams. His vision was laced with multicoloured afterimages, like slashes across his retinas. A ba lance firefight in darkness was inevitably short-lived. After a while your eyes became dazzled and you were firing more or less blind. It would come down to hand-to-hand soon. He was prepared for that.

He scored a hit. A Nephthysian shrieked and plummeted from his vantage point, hitting the ground two seconds later with a crunch. David then winged another, whose own blaster shot went astray and lanced through one of his colleagues in the valley. Enemy fire came David's way but struck the column harmlessly. At this range, the blaster beams could not penetrate solid stone.

A few of the paratroopers had retreated to the mouth of the Siq and were putting up a strong resistance from there. They took it in turns. One would shoot, eliciting return fire from the Nephthysians. Then the next paratrooper would aim a blast at where the enemy shot had come from.
