"Perhaps the attraction you seem to hold for the Oan can be put to good use," he said aloud. "The sphere is a distance away from the Oan camp. All of the rat men cannot be guarding it. Perhaps, by revealing yourself, you can lure the guards away from their post."
He repeated his plan to the others.
"But they'll kill her," gasped Charlotte.
"She will be a woman alone," said Ro. "The Oan prefer to capture women when they can."
"Then she'll be captured," the professor said. "It's much too risky."
Ro laughed.
"Do you think I will let her go alone? I will be close by. Na can lead the rat men through a narrow part of the valley. I will be above on the cliffs, waiting to pelt them with stones. Carlson or Grimm can be with me to roll an avalanche of rocks on their heads.
"In the meantime, you can take over the unguarded sphere. The rest will be easy."
The professor smacked his fist into his palm.
"It might work at that. Grimm can go with you. Carlson and Charlotte will go with me."
