Free Sanctus by Simon Toyne Page B

of the recent technological improvements, it had been devised and engineered by one man: Athanasius’s great friend, Father Thomas.
    From the moment Father Thomas had entered the Citadel over a decade previously he had been treated differently from the usual intake. Like most of the inhabitants of the mountain, his past was unknown, but whatever he had done in his life outside, it became immediately clear that he was an expert in the preservation of ancient documents and a genius with electronics. In his first year he had been given special authority, by the Prelate himself, to totally overhaul and update the library. It was a task that took him nearly seven years to complete, the first year alone spent purely on experimenting with different light frequencies and studying their effect on various inks and writing surfaces. The lighting system he had then designed and built was brilliant in its simplicity and had been inspired by the very first scholars who’d walked through the library with a single candle illuminating only their immediate surroundings, whilst leaving the rest of the collection in total darkness.
    Using a system of movement, pressure and heat sensors, Father Thomas had created an environment in which anyone entering the library was tracked by a central computer that provided a narrow column of light, sufficient to illuminate no more than their immediate surroundings. This light would then follow them throughout the library, constantly pushing away the darkness as they walked through it, without contaminating any area in which they were not working. The system was so sensitive that each monk could be identified by tiny differences in their body temperature and slight fluctuations in air displacement due to their unique size and weight. It meant the computer could not only monitor the movement of each visitor, it also knew who they were and where they went, so acted as an added security measure policing the monks’ usage of the library.
    Athanasius left the entrance hall now, following the thin filament of dim guide lamps set into the floor, marking the way through the darkness. Occasionally he came across other scholars flitting around like fireflies, trapped in their personal haloes of light, each one dimmer the further he progressed into the great library.
    Father Thomas’s other great innovation had been to zone the library according to age, ink and paper types, and to adjust the lighting in each area to suit their particular properties. So, as Athanasius ventured deeper into the places where increasingly older and more fragile texts were kept, so his own circle of light became gradually more muted and orange. It was as if he were walking backwards through time, experiencing the same conditions that would have illuminated the documents when they had first been written.
    Furthest from the entrance was the smallest and darkest chamber of all. The oldest, most delicate and most precious texts were housed here. Scraps of vellum worn thin by time and ancient words scratched lightly on brittle stones. The glow in the forbidden vault, on the very rare occasions it shone at all, was the deep and sombre red of the embers of a dying fire.
    Only three people had perpetual right of entry to this room: the Prelate, the Abbot and Father Malachi, the chief librarian. Others could be granted special authority by any of these three to enter the vault, but it happened rarely. If someone entered the space without the correct authorization, either by design or mistake, the lights would remain off and a silent alarm would alert the guard permanently stationed by the entrance who would surge through the dark halls to deal with the intruder.
    Punishment for entering the forbidden vault was traditionally harsh, always public, and served as the greatest single deterrent for ever being inclined to do so. In the past transgressors had been brought before the fully assembled college of priests and monks to have their eyes put out,
