A bundle of letters, bearing the seal of someone with ties to the emperor, now long dead. These letters end a couple of years before the fall of the empire, and speaks of an investigation. Whomever wrote the letters was in charge of finding the cause for growing animosity against the empire, to the point where there had been rioting peasants.
Several agents were involved in this investigation, and from the letters it is clear that some vanished or died along the way. There is mention of several other tangents, that the investigation followed, but even the ones that lead to a potential threat (from mindflayers and dragons to illusionists and cultists), never seem to be the cause of the revolting peasants.
Magic of some sort was behind it, and the investigator suspected that whatever was happening in these neighboring small towns, was part of a larger plot. The letters do not offer any conclusion, and it is uncertain exactly who the writer was – possibly a relative to the emperor, or someone holding a special place in his council. Whomever it was, he or she signed the letters “Yaro”.
