Three great daggerlike crosses stormed up the frozen river. They drove into the fangs of the wind in a rigid V. That fierce and dreadful shadow-of-touch preceded them, flaying the mind with terror. Upon each cross stood five black-clad silth, one at each tip of each arm, the fifth at the axis. The incessant north wind howled around them and tore at their dark robes. They seemed to notice it not at all.

"They are coming," Marika shouted to Grauel and Barlog, who crowded her against the windowsill.

An explosion thundered out behind them. It threw them together. Marika gasped for breath. Grauel turned, pointed her rifle. It barked in unison with that of the tradermale Bagnel as savages appeared in the dust swirling in the gap created by the explosion.

Marika clung to the windowsill, looking out, waiting for death.

The rushing crosses rose as they neared Akard, screaming into lightly falling snow, parting. Marika slipped through her loophole into the realm of ghosts and followed them as they plunged toward the attacking nomads, spreading death and terror.

Grauel and Bagnel stopped firing. The nomads had fled the breach. In minutes the entire besieging horde was in full flight. Two of the flying crosses harried the savages northward. The third returned and hovered over the confluence of the forks of the Hainlin, above which Akard brooded on a high headland.

Akard's pawful of survivors crowded the window, staring in disbelief. Help had come. After so long a wait. In the penultimate moment, help had come.

The cross drifted closer till the tip of its longest arm touched the fortress on the level above the communications center. Marika pushed weariness aside and went to meet her rescuers. She was only fourteen, as yet far from being a full silth sister, but was the senior silth surviving. The only silth surviving. Through eyes hazed with fatigue and reaction, she vaguely recognized the dark figure which came to meet her. It was Zertan, senior of the Reugge Community's cloister at Maksche.
