The unicorns were released when the ore was unloaded at the foot of the hill before the caves and Schroeder went to the new waterwheel, where the new generator was already in place. There George Craig told him of the unexpected obstacle that had appeared.

“We’re stuck,” George said. “The aluminum ore isn’t what we thought it would be. It’s scarce and very low grade, of such a complex nature that we can’t refine it to the oxide with what we have to work with on Ragnarok.”

“Have you produced any aluminum oxide at all?” Schroeder asked.

“A little. We might have enough for the wire in a hundred years if we kept at it hard enough.”

“What else do you need⁠—was there enough cryolite?” he asked.

“Not much of it, but enough. We have the generator set up, the smelting box built and the carbon lining and rods ready. We have everything we need to smelt aluminum ore⁠—except the aluminum ore.”
