Fragments of the Fiend Lords

Found in the library collection of Agnes Marshcradler, the Fragmets of the Fiend Lords is a science and medicinal report.
Fully researched by Vyodros.

My first discovery of the fragments was by chance more than any solitary investigation. A scheme and diagnosis that would be passed for madness or illness, should any other discover it. Many would not call them fragments, as it would infer that they are shards, or broken pieces of an inanimate object. But in this case, these fragments are very animate, and very alive.  This ploy by the Demon Lords is a new one, creative and ingenious, if it proves to be true. Further investigation is required, along with greater research and the expertise into both medicine and the arcane.

The source seems obvious, but the manner in which these fragments were forged remains a great mystery. It was only when visiting a colleague at the Cerebral Sanctuary was I able to begin this journey of discovery. It was here that I met a man by the name of Ekver Hammel, and the stories that he told were both fantastical and enchanting, but worrying none-the-less. There was no doubt that evil was inherent within his very being, but his story bordered on far-fetched and impossible.

It isn’t possible. All practice of the arcane, rituals and magical observations have returned as negative. This so-called ‘fragment’ is a myth, a story and will one day no doubt become an old wives tale that adventurers tell around a campfire. I have entertained this long enough to become my own story, one of hysteria amongst my colleagues. The mutation upon Evker’s body must have a reasonable explanation, one that is physiological, biological or at the very least medicinal. I have since  sanctioned a full report and period of experimentation using as many herbs and other properties as deemed necessary by the apothecaries of Tosima.

His mind is deteriorating. Time is running out to discover the truth behind it all. The fate of my career and future rests solely on the longevity of this man’s life. He will not survive in the Cerebral Sanctuary. Though nefarious, my examinations of the man cannot continue in earnest and with full effect. The Forsaken are cut-throat criminals, but they can serve a purpose here. I need to move Ekver to my laboratory in Stonevale before it is too late. I believe there is truth in his story. His madness is unquestionable, but I do not believe it stems from a lie or madness, and it is instead a side effect of his creation.

Extracted and safe, but I cannot say for how long. The Forsaken made a mess of their work and failed to do so discreetly. The Coalition have suddenly taken a great interest in Ekver, now an independent party has done so. They are scouring the lands for him and I, no doubt because they know the truth and wished nothing more than to bury it and avoid hysteria and chaos in their region. But they cannot hide this. If my suspicions are correct, then Ekver is only the first Fragment of the Fiend Lords to have been and there are others out there. I intend to venture south, out of the Coalition lands in search of more of these fragments and continue my research.  Kethri will continue my work here in Stonevale, I trust no one more than her.
