"Why those?" I asked.

"You may need an extra sword hand," she replied. "You do not know against how many foemen you will be pitted."

"Wear them, if you like," I said, "but remain in the ship where you will be safe. Jat Or and I will take care of the fighting."

"I shall go with you and fight with you," said Zanda, quietly but emphatically.

I shook my head. "No," I said; "you must do as I say and remain on this ship."

She looked me steadily in the eye. "Against my will, you insisted upon making me a free woman," she reminded me. "Now I shall act as a free woman and not as a slave. I shall do as I please."

I had to smile at that. "Very well," I said; "but if you come with us, you will have to take your chances like any other fighting man. Jat Or and I may be too busy with our own antagonists to be able to protect you."

"I can take care of myself," said Zanda, simply.

"Please stay on board," pleaded Jat Or solicitiously; but Zanda only shook her head.

Our ship had settled quietly to the ground beside that of Gar Nal. I caused the door in the port side to be opened and the ladder lowered. Still there was no sign of life either on the other craft or elsewhere about the castle. A deathly silence hung like a heavy mantle over the entire scene.

Just a moment I stood in the doorway looking about; and then I descended to the ground, followed by Jat Or and Zanda.

Before us loomed the castle, a strange weird building of unearthly architecture, a building of many towers of various types, some of them standing alone and some engaged in groups.

Partially verifying Fal Sivas's theory of the tremendous mineral wealth of the satellite, the walls of the structure before us were constructed of blocks of precious stones so arranged that their gorgeous hues blended and harmonized into a mass of color that defies description.

At the moment, however, I gave but cursory attention to the beauties of the pile, turning my attention instead to Gar Nal's ship. A door in its side, similar to that in our ship, was open; and a ladder depended to the ground.

I knew that in ascending that ladder, a man would be at great disadvantage if attacked from above; but there was no alternative. I must discover if there were anyone on board.

I asked Zanda to stand at a little distance, so that she could see into the interior of the ship and warn me if an enemy exhibited himself. Then I mounted quickly.

As the ship was already resting on the ground, I had only to ascend a few rungs of the ladder before my eyes were above the level of the cabin floor. A quick glance showed me that no one was in sight, and a moment later I stood inside the cabin of Gar Nal's ship.
