Skulduggery nodded as Tipstaff walked away, already checking his clipboard for the next item on his to-do list. Skulduggery waited with his hands in his pockets, standing as still as any of the statues around him. Stephanie wasn’t nearly so patient, so off she went, glad for the chance to get away from him. He had his moments of levity, moments when the old Skulduggery would emerge, but they were few and short-lived. His mind was on other things. His mind was on Valkyrie Cain.

She didn’t need to be around him when he was thinking about her.

She left the marble and the brightly-lit corridors and entered the area that had become known as the Old Sanctuary, what remained of the original building with its concrete walls and flickering lights and dancing shadows. Not many sorcerers bothered coming down here, and that’s why Stephanie liked it. Those other sorcerers looked at her uneasily. To them, she was the reflection of the world-breaker, the cheap copy of the girl who was going to kill them all. They didn’t trust her. They didn’t like her. They certainly didn’t value her.

She stepped into the Accelerator Room.

“Hi,” she said.

The Engineer turned. The smiley face that Clarabelle had drawn on to its smooth metal head was still there, and gave the robot an endearingly cheerful expression. Parts were missing from its sigil-covered body, and in those gaps a blue-white light pulsed gently, almost hypnotically.

“Hello, Stephanie,” the Engineer said. “How are you today?”

She shrugged. The Accelerator stood in the middle of the room like an open vase, the uppermost tips of its wall almost scraping the ceiling. Circuitry ran beneath the surface of its skin, crackling brightly. It drew its power from a rift between this world and the source of all magic, a rift the size of a pinprick that the machinery had been built around.

“It’s getting brighter,” she said.

“Yes it is,” said the Engineer. “Every time the power loops, it grows.”

It had originally given them twenty-three days, eight hours, three minutes and twelve seconds until the Accelerator overloaded. Tasked with extending that deadline if at all possible, it had tinkered with the machine, re-routing its power flow and usage, until seven more days had been added to the countdown. But that brief moment of breathing space had been swallowed up as time marched onwards.

“How long left before it all goes kaboom?” Stephanie asked.

“Fourteen days, seven hours and two minutes,” the Engineer said. “Although the sound it makes will not be kaboom. If and when the Accelerator overloads, the sound will more than likely be a very loud fizz. Possibly a whump.”

“Right. So not very impressive, then.”

“Indeed. The effects, however, will be most impressive.”
