Hotep-Ra puts a Stop on the Hex. The little pyramid sits heavy in his hand, a fiery gold, glinting in the sun. Hotep-Ra smiles. “You will be the Keye,” he tells the pyramid.

Once again Hotep-Ra is on the Palace landing stage, saying a sad farewell to the Queen. This time he is not alone. Talmar Ray Bell has insisted on coming with him—Hotep-Ra is so weakened by his fight with the Darke Wizards that Talmar fears he will not be able to make the journey on his own.

Hotep-Ra gives the Queen a farewell gift. It is a little book called The Queen Rules. It is bound in soft red leather with gold corners and an intricate clasp, and on it is embossed a drawing of the Dragon Boat. It is not his fault that a thousand or so years later the binding falls to pieces, the pages drop out and the Committal is lost. No bookbinder, not even a Magykal one, can make a book last forever. But memories will last, if they are handed down through the generations.

Hotep-Ra takes the Queen’s barge to the Port. There, a ship is waiting for him and they set sail. The sea is calm and the sun shines. Hotep-Ra spends most of his time on deck, storing up memories of the open air and sea breezes to tide him over the long enclosed times ahead in his final resting place—the House of Foryx.

Night falls and the ship approaches the Enchanted—and much feared—Isles of Syren. Hotep-Ra sees the Lights shining from the four cat-shaped lighthouses that surround the Isles. He waits until the ship is safely past and all but he have gone below to sleep. Then, by the light of the full moon, Hotep-Ra drops the Two-Faced Ring into the ocean. As it tumbles down through the water, moonlight glints on the gold and an ugly cowfish snaps it up.

And there begins the long journey of the Two-Faced Ring back to the Wizard Tower. Where it now lies. Waiting.

WHAT LIES BENEATH

In the Vaults of the Manuscriptorium, The Live Plan of What Lies Beneath was unrolled on a large table. Lit by a bright lantern that hung above the table, the large and fragile sheet of opalescent Magykal paper lay weighted down by standard Manuscriptorium paperweights—squares of lead backed with blue felt. The Live Plan of What Lies Beneath was a map of all the Ice Tunnels that ran below the Castle—apart from the section that traveled out to the Isles of Syren. As its name suggested, the Live Plan was a little more than just a plan. Magykally, it showed what was happening in the Ice Tunnels at that very moment.

Gathered around it were the new Chief Hermetic Scribe, O. Beetle Beetle; Romilly Badger, the Inspection Clerk; and Partridge, the new Scribe of Maps. If you had walked into the Vaults at that moment it would not have been clear who actually was the Chief Hermetic Scribe. Beetle’s long blue-and-gold coat of office had been banished to a nearby hook because its gold-banded sleeves scratched the delicate Live Plan and he was wearing his comfortable old Admiral’s jacket, which kept out the chill of the Vaults. With his dark hair flopping forward over his eyes, Beetle looked very much at home as he leaned over the Live Plan, concentrating hard.

Suddenly Romilly—a slight girl with light brown hair and what Partridge thought was a cute, goofy smile—squeaked with excitement. A faint luminous splodge was moving along a wide tunnel below the Palace.

“Well spotted,” said Beetle. “Ice Wraiths are not easy to see. I reckon that’s Moaning Hilda.”

“There’s another one!” Romilly was on a roll. “Ooh . . . and look, what’s that?” Her finger stabbed at a tiny shadow near the old Great Chamber of Alchemie and Physik.

Partridge was impressed. There was a minuscule blip at the end of Romilly’s finger. “Is that an Ice Wraith too?” he asked.

Beetle peered closer. “No, it’s too shadowy. And slow. Look—it is hardly moving at all compared to Moaning Hilda, who is way over there now. And it is too well defined; you can see it actually has a shape.”

Romilly was puzzled. “Like a person, you mean?”

“Yes,” said Beetle. “Just like a—bother!”

“It’s gone,” said Romilly sadly. “That’s a shame. It can’t have been a person then, can it? Someone can’t suddenly disappear. It must have been a ghost.”

Beetle shook his head; it was too solid for a ghost. But the Live Plan was telling him that all the Ice Tunnel hatches remained Sealed, so there was nowhere the person could have gone. Only a ghost could disappear from the middle of an Ice Tunnel like that.

“Weird,” he said. “I could have sworn that was human.”

It was human—a human named Marcellus Pye.

Marcellus Pye, recently reinstated Castle Alchemist, had just dropped down through a hatch at the bottom of an unmapped shaft, which went close enough to an Ice Tunnel to show on the Live Plan. As soon as he was through the hatch Marcellus knew he was safe—the Live Plan did not show anything lower than this level.
