Perhaps because during all this period of waiting he had been half expecting it, Simon identified the source first, and sped for the stair which, three floors higher, gave upon the sentry go of the roof.

He did not reach that level. Screams and cries from above, the clash of metal against metal was warning enough. Slowing his pace, Simon drew his gun. And it was good he was cautious for he was midway to the second level when a body rolled down, missing him by a scant inch. It was a Sulcarman, his throat a ragged wound still pumping blood to spatter wall and stair. Simon looked up into a wild confusion.

Two Guardsmen and three of the seafarers still fought, their backs against the wall on the landing of the next level, keeping at bay invaders who attacked with the single-minded ferocity their kin had displayed at the road ambush. Simon snapped a shot, and then another. But a wave of beaked helms poured unceasingly from above. He could only guess that in some way the enemy had come by air and now held the top floors of the keep.

There was no time to speculate upon their method of getting there — it was enough that they had managed to break through. Two more of the seafarers, one of the Guard were down. The dead and wounded, friends and foe alike were disregarded by the beaked helms. Bodies slipped downstairs — they could not be stopped there. The plug must come below.

Simon leaped for the first landing, kicking open the two doors fronting on it. The furniture favored by Sulcar was heavy stuff. But the smaller pieces could be moved. In that moment Simon summoned up strength he did not know he possessed, jerking and pushing articles out to choke the stairwell.

A beaked head faced him through the upraised legs of a chair used to top his efforts, and a sword point struck for his face. Simon crashed the chair over on that helm. There was a smarting cut on his cheek but the attacker was not a part of the barricade.

“Sul! Sul!”

Simon was elbowed to one side and he saw Magnis’ face, as red as its tawny bristle of mustache, loom up as the trader chopped down, smashed up at the first wave of invaders to reach the stair barrier and claw at the stuff which formed it.

Aim, fire, aim again. Throw away an empty dart clip, reload to fire anew. Straddle a Guardsman down moaning, until the man could be dragged back into whatever safety anyone could find in the keep now. Fire — Fire!
