According to the skylight crowning the west wing's atrium, a cloudy moonless night had fallen suddenly.

With a couple of hundreds of meters of solid rock above the research facility, and the 'skylight' being simply a large arrangement of lighting panels mimicking sunlight, it meant that someone had cut the power lines.

High above the floor, 'R' knelt on the armoured belly of the black beast hanging from the ceiling and fiddled inside an opened panel.

"Move it, 'B'!" he hissed abruptly.

The creature let go.

Ten meters from the ground it submitted to gravity, swung the long tail around to give the rest of the body momentum enough to right itself, and folded the long arms around the body slipping off its chest.

'B' had not yet fallen on its feet like a cat when a sharp jab of lightning shot over the position it had just vacated.

All of the power usually sustaining a whole wing of the subterranean facility suddenly … left its customary ways and moved along other, less suited channels. The air smelled burned. Sparks rained from the walls in total darkness. Even the emergency lights were dead.

Part of the blue print on the master security screen flickered once and vanished.
