In the Myriadic Year of Our Lord – the ten thousandth year of the King Undying, the kindly Prince of Death! – Gideon Nav packed her sword, her shoes, her dirty magazines, and she escaped from the House of the Ninth.

She didn't run. Gideon never ran unless she had to. In the absolute darkness before dawn she brushed her teeth without concern and splashed her face with water, and even went so far as to sweep the dust off the floor of her cell. She shook out her big black church robe and hung it from the hook. Having done this every day for over a decade, she no longer needed light to do it by. This late in the equinox no light would make it here for months, in any case; you could tell the season by how hard the heating vents were creaking. She dressed herself from head to toe in polymer and synthetic weave. She combed her hair. Then Gideon whistled through her teeth as she unlocked her security cuff, and arranged it and its stolen key considerately on her pillow, like a chocolate in a fancy hotel.

Leaving her cell and swinging her pack over one shoulder, she took the time to walk down five flights to her mother's nameless catacomb niche. This was pure sentiment, as her mother hadn't been there since she was little and would never go back in it now. Then came the long hike up twenty-two flights to the back way, not one light relieving the greasy dark, heading to the splitoff shaft and the pit where her ride would arrive: the shuttle was due in two hours.

Out here, you had an unimpeded view up a pocket of Ninth sky. It was soupy white where the atmosphere was pumped in thickest, and thin and navy where it wasn't. The bright bead of Dominicus winked benignly down from the mouth of the long vertical tunnel. In the dark, she made an opening amble of the field's perimeter, and she pressed her hands up hard against the cold and oily rock of the cave walls. Once this was done, she spent a long time methodically kicking apart every single innocuous drift and hummock of dirt and rock that had been left on the worn floor of the landing field. She dug the shabby steel toe of her boot into the hard-packed floor, but satisfied with the sheer improbability of anybody digging through it, left it alone. Not an inch of that huge, empty space did Gideon leave unchecked, and as the generator lights grumbled to half-hearted life, she checked it twice by sight. She climbed up the wire-meshed frames of the floodlights and checked them too, blinded by the glare, feeling blindly behind the metal housing, grimly comforted by what she didn't find.

She parked herself on one of the destroyed humps of rubble in the dead centre. The lamps made lacklustre any real light. They explosively birthed malform shadow all around. The shades of the Ninth were deep and shifty; they were bruise-coloured and cold. In these surrounds, Gideon rewarded herself with a little plastic bag of porridge. It tasted gorgeously grey and horrible.
