Giles sheathed his sword and bowed. The Sarjeant-at-Arms made his guns disappear again, and folded his arms tightly with a definite Look at me I’m not sulking even though I have cause expression on his face. The Matriarch sighed audibly.

“Don’t just stand there, Sarjeant! Armour up! Everyone, armour up!”

She had a point. We all subvocalised the activating Words, and just like that the War Room was full of gleaming golden figures. It felt good to be back in the gold again, to feel strong and fast and sharp. Sometimes putting on the armour is like snapping fully awake from a long doze. Everyone not preoccupied at a workstation peered suspiciously about them, ready for action, golden blades and other weapons extruding silently from golden fists. There was a rising tension in the War Room, a strong feeling of something coming, pressing inexorably closer. We could all feel it, pressing in on us from all sides at once. Molly stood close beside me, her arms lifted in the stance of summoning, ready to throw seriously nasty magics at anything even remotely threatening. Mr. Stab looked . . . politely interested. And the Armourer, not surprisingly, had pulled a really powerful-looking weapon out of nowhere and was swivelling it back and forth in search of a target, while everyone else hurried to get out of his way.

Heaven help anyone who dares to face the Droods on their own territory.

A rising babble of voices filled the War Room as the various technicians struggled to understand what was happening. Whatever was coming slammed through layer after layer of protections, and the tension in the air was almost physically painful. Martha Drood, back in armour for the first time I could remember, moved from station to station, peering over shoulders and dispensing a cautionary word or a bracing murmur, as required. If she was reduced to rallying the troops, we really were in trouble. A rising tone rang out on the air, sharp and distinct, as though approaching from somewhere inconceivably far away.

“It’s here!” Howard shouted. “It’s materialising!”

“Where?” said Martha. “Where exactly in the Hall?”

“Here!” screamed Howard. “Right here in the bloody War Room!”
