“I should have known from the black scowl which Grim Hagen had worn those many months that he would not be stopped by one defeat. You will remember, Odin, how I told you of the little flying machines that we strapped on our backs in the old days and went sailing through the air. They were outlawed. But during the time that Grim Hagen held the tower he must have found the plans for the flying machine, or maybe even one of the machines. For when his men attacked us, each one had such a machine. And each man carried dozens of little glass eggs. When they threw them they exploded and dissolved nearly everything for twenty foot around.
“Oh, we fought. We killed many. But it is hard to fight the hawk. One by one they blew up our ships. Then, carrying Maya and a few other prisoners with them, they flew out to sea like a flight of evil birds—no, not birds, for not even the hawk is evil. What was the word that you used for the leather-winged, toothy things that live in the forest?”
“Dactyls,” Jack Odin prompted.
“Yes, that’s it,” Gunnar said as he stared into the fire. “Dactyls. I like that word. It has an evil, bloody ring to it.”
He stopped talking to take a huge bite of stale bread that nearly choked him. Then he continued his story.
“Meanwhile, in the city of the Scientists, the same kind of fighting had been going on. We learned later that when Grim Hagen’s men winged their way in from the sea, his army had already retaken the Tower. Ato and his soldiers were scattered. Half of them were dead. So, after scattering their explosive eggs across the city, and killing the very old and the very young, Grim Hagen and his men took refuge in the Tower and prepared to withstand our siege. They had learned much from their first defeat, and this time they held it well.
“As soon as we could patch up our ships, we came a-following and joined forces with Ato’s soldiers. We assaulted the Tower day after day. Until the ground and the walks around it were black with our dried blood. But they held out. Not once did they try a counter-attack. We should have guessed at what Grim Hagen was planing. But we didn’t until one of the prisoners escaped. His name was Zol, and he was a friend of Maya’s father. Poor fellow, he is dead now, but if we of Opal went in for monuments we would build one a mile high for Zol. He told us that Grim Hagen was readying the Old Ship for flight into space. Also, he planned to leave the sea gates open.
“Zol saved us. Or saved some of us and a part of Opal. Ato began training divers against the day when the tunnel would be flooded. We moved as many people as we could onto the ledges high up on the walls of Opal. We got our great pumps ready to cope with the flooding.
“Also, Ato and I renewed our assault upon the Tower. But they bested us. They had learned too many of the old secrets. Most of the young men of the Neeblings died there against the walls. That is how we keep our promises, Nors-King.
