Prologue 
FIVE HUNDRED YEARS AGO
The Vampirate captain stepped into the room, dressed in his familiar garb of mask, gloves, and cape. He bowed to Mosh Zu, who acknowledged him politely.
“Cardinal North.”
The two of them turned toward the doorway, waiting for the others to arrive.
Now an identically dressed figure arrived at the threshold and strode over to greet them.
“Cardinal East,” Mosh Zu proclaimed, before he and the first captain bowed at the new arrival, who tilted his head reciprocally.
Mosh Zu’s assistant, Olivier, moved from the center of the room over to the doorway as a third, then fourth, figure arrived. They nodded perfunctorily at Olivier, then joined Mosh Zu and the others.
“Welcome, Cardinals South and West,” Mosh Zu said. “Now that all four of you are assembled, it is time for the ceremony to begin. Cardinals, please take your positions.”
At these words, the four captains moved to stand on the points of the mosaic compass on the floor—North, East, South, and West, in accordance with their title. Mosh Zu remained inside the circle. He was surrounded by the four Vampirate captains. They each raised their arms and joined their gloved hands, forming an unbroken circle. Their four capes began to billow. As they did so, they sparked with light, as if the joining of their hands had created a power surge. The light crackled for a moment, then diminished to a flicker. The capes continued to move but more gently now, like sails in the breeze.
“I shall not waste any time,” Mosh Zu said. “It is rare for you to come together, but I had to call you here tonight.” He paused. “A prophecy has been revealed to me, one I must share with you. If I have interpreted it correctly, this prophecy has the power to change everything.”
“What is the prophecy?” The captains spoke as one, their voices rolling over one another like soft waves, in a strange whisper.
“A time of war is coming to the oceans,” Mosh Zu announced.
“War?” answered the captains, their voices once more united in that strange, watery whisper. “War between us and the pirates?”
“No,” Mosh Zu said. “War within our own realm. Our precious union will splinter and the greatest threat will come from within.”
“What is this threat?” asked the captains. “Give it a name!”
“I do not know its name,” Mosh Zu said. “But the chief warmonger belongs to one of your crews. Be alert to him or her.”
“When will this war commence?” the captains asked Mosh Zu.
“Soon, I think,” Mosh Zu replied.
“Soon?” There was a note of scorn in the captains’ whisper. “Soon is an unhelpful term for immortals like us.”
“Agreed,” Mosh Zu answered. “But it is time to make plans.”
“What more does your prophecy tell us?” asked the captains.
“Our hope rests with twin children, who have yet to be born.”
“What are their names?” inquired the captains.
“Their names are not yet clear to me,” Mosh Zu said. “But they are the children of this warmonger and their powers will be unprecedented. Their role in the future of our realm will be great, and, when war comes, they and they alone will have the power to deliver our victory.”
“We must find these twins, these children of the warmonger,” the captains said. “We must search for them across the oceans.”
“I repeat,” said Mosh Zu. “They have yet to be born. When the time is right,
There was silence for a moment; then the captains spoke once more. “Is this the end of your prophecy?”
“There is one more thing,” Mosh Zu said. “In order to bring about peace, one of the twins must enter the void. I saw darkness surround one twin, and auguries that signified death.”
“The death of mortals or our immortal death?” pressed the captains.
“I cannot be sure,” Mosh Zu said. “But my sense was that though the child will be born of a Vampirate and will therefore be immortal, he or she will have to journey to the realm of the mortal dead in order to achieve peace. That is as much as I could ascertain.”
“We thank you,” the captains said, their whisper more haunting than ever. “We will take our leave now and ponder these portents.”
At these words, their capes began to undulate more strongly and to spark with light once again. A mist began to circle around them. Soon it had completely surrounded them and it was no longer possible to discern their outlines.
As the mist receded, Mosh Zu found himself alone in the center of the mosaic compass.
The Four Cardinals had taken their leave. They would not meet again for a very long time.
TICK-TOCK
The ancient offices of Mizzen, Mainbrace, Windvane, and Splice, “lawyers to the pirate community, by appointment to the Pirate Federation, since 2015,” were at the top of a cliff and took the form of the upper three decks of a pirate galleon, which had been braced directly onto the rock itself. The impression was of a ship sailing— indeed flying—right off the peak into the bay far below. The main conference room of the famous maritime firm of
