They drew in with the silent, deadly promise of their kind, their very silence heavy with menace. Simon chose quickly and darted to meet them. He skidded to the right and tackled the man next to the wall about the shins, bringing him down in such a way as to guard his own back.

The smooth flooring of the passage was an unexpected aid. The impact of Simon’s tackle carried both past the man’s two companions. Simon stabbed up with his knife and felt the sear of a blade across his own ribs under his arms. Coughing, the guard rolled away, and Simon snatched the dart gun from his belt.

He shot the first of the others just in time and the stroke of the sword aimed for his neck sank instead into the wounded man. That brought him a precious second to sight on the third and last of the enemy.

Adding two more dart guns to his weapons he went on. Luckily this hall ended in no concealed doors but a stair, cut of stone and winding up against a wall also of stone, both of them in contrast to the smooth gray surfacing of the passages and rooms through which he had already come.

His bare feet gritted on that stone as they took the steps. At a higher level he came out in a passage akin to those he had seen in the hold of Estcarp. However functional-futuristic the inner core of this place might be, its husk was native to the buildings he knew.

Simon took cover twice, his gun ready, as detachments of the Kolder-changed natives passed him. He could not judge whether a general alarm had been given, or whether they were merely engaged in some routine patrol, for they kept to a steady trot and did not search any side ways.

Time in these corridors where there was no change of light had no meaning. Simon did not know whether it was day or night, or how long he had been within the fortress of the Kolder. But he was keenly conscious of hunger and thirst, of the cold which pierced the single garment he wore, of the discomfort of bare feet when one had always gone shod.

If he only had some idea of the inner plan of the maze through which he was trying to escape. Was he on Gorm? Or in that mysterious city of Yle which the Kolder had founded on the mainland coast? In some more hidden headquarters of the invaders? That it was an important headquarters he was certain.
