Thor stood in the arch of the gates and stared back at the balcony where the black urn lay tilted. That green stuff! His head was churning, trying to catch the elusive thought that dipped and darted out of reach of his mental hands. He shook his head.

"There's something about Aava—"

"Thor, please. There isn't time. Yorg says at any moment Aava will send androids to surround us. They will fetch other urns. We will die."

He snapped awake to the knowledge that he was walking with a frightened Karola behind the others, that ahead of him the women and the men were running. They had gone through the gates and were spreading out over the streets and alleys of the cyclopean city.

"Yorg! Tor Kan! Gordon!"

The Englishman heard him, came to him through the press, his longbow strung with a ready arrow.

"Jolly brush, what? Found I haven't lost my eye for a target. Got thirty of the blighters, myself."

Thor said, "We'll never escape Aava in his city. There's only one chance. We have to use the gatestone, and scatter. Can you get the others?"

Peter threw back his head and sent a shrill cry ululating across the streets. The men and women paused, looking back over their shoulders. Gordon waved an arm. Fearfully, the listeners began to return.

Thor lifted out the ruby, told the others to grasp it, as many as possible. He said, "Once we get into that other world, it will be easy for us to lose ourselves. Aava and his Black Priest do not know we possess a gatestone. They will search for us here in the city. While they hunt here, we will be far away."
