As an individual man weakens and sickens, so the Imperial Guard forces as a whole began to fail and falter as their best were taken by the pestilence. Within two months, Warmaster Rhyngold’s staff were doubting the continued viability of the entire campaign. By the third month, Uhlren’s Pox had also broken out (apparently miraculously and spontaneously, given its unknown process of dispersal) on Genovingia Minor, Lorches and Adamanaxer Delta. Four separate centres of infection, right along the leading edge of the Imperial advance through the sector. At that point, the contagion had spread to the civilian population of Genovingia itself, and the Administratum had issued a Proclamation of Pandemic. It was said the skies above the cities of that mighty world were black with carrion flies, and the stench of biological pollution permeated every last acre of the planet.

I had a bureaucratic posting on Lorches at that time, and became part of the emergency body charged with researching a solution. It was weary work. I personally spent over a week in the archive without seeing daylight as I oversaw the systematic interrogation of that vast, dusty body of knowledge.

It was my friend and colleague Administrator Medica Lenid Vammel who first called our attention to Pirody and the Torment. It was an admirable piece of work on his part, a feat of study, cross-reference and memory. Vammel always had a good memory.

Under the instruction of Senior Administrator Medica Junas Malter, we diverted over sixty per cent of our staff to further research into the records of Pirody, and requests were sent out to other Genovingian worlds to look to their own archives. Vammel and I compiled the accumulating data ourselves, increasingly certain we had shone a light into the right shadow and found a useful truth.

Surviving records of the Torment incident on Pirody were painfully thin, though consistent. It was, after all, thirty-four years in the past. Survivors had been few, but we were able to trace one hundred and ninety-one possibles who might yet be alive. They were scattered to the four cosmic winds.

Reviewing our findings, Senior Malter authorised personal recollection, such was the gravity of the situation, and forty of us, all with rank high administrator or better, were despatched immediately. Vammel, rest his soul, was sent to Gandian Saturnalia, and was caught up in a local civil war and thereafter killed. I do not know if he ever found the man he was looking for. Memory is unkind there.

And I, I was sent to Symbal Iota.

Symbal Iota, where it is not covered in oceans that are the most profound mauve in colour (a consequence, so I understand, of algae growth), is a hot, verdant place. Rainforest islands ring the equatorial region in a wide belt.
