Back to the Beginning…How Sandy Met Dr. Luis Merlo

Back to the Beginning…How Sandy Met Dr. Luis Merlo

There is still much to be learned about the seemingly sane Dr. Luis Merlo, who approached Sandy a few years back with some odd sketches of creatures that appeared to be real, but didn’t follow any anatomical rules.

In fact they seemed strangely familiar to Sandy because of his knowledge of H.P. Lovecraft’s fiction. Here is an early letter Sandy received that started him down the path to publishing Dr. Merlo’s works in The Anatomical Guide to Lovecraftian Horror.


“Dear Mr. Petersen,

I am delighted to know you are interested in my work. Through years of research reviewing the literature and scouring the field, I have come across enough evidence to build a compendium on the entities, even if some polishing is still required.

I strongly believe that the public and the scientific community deserve to know about them and, because of your vast expertise on the field, I trust you to be the person to publish it.

However, I must insist that these are not “Lovecraftian monsters” as you called them. The subjects of my study are mostly unknown creatures depicted in ancient lore and legend, of which HPL managed to get a frightening amount of information, which he simply conveyed through his tales.

That was the reason I chose his framework: He saw the beyond and was outstandingly accurate in classifying these creatures of myth.

My intent is not to scare, but to warn and educate. Creatures like the Zin Ghast (depicted in the attached sketch) roam freely in the spaces between realities, and yet can be fully understood by application of the scientific method! This is groundbreaking science Mr. Petersen, not magic.

I have attached more notes and images to this letter for your consideration, please excuse the stains.


P.S. I am sorry to limit my communication to physical post, but I cannot trust electronic means. Please do not try to contact me via email.”

“The information in the Guide could also be useful to an Investigator with a medical background, who seeks to learn how to extract a particular gland from a specific part of the horror’s anatomy. Once attained, the gland might then be combined with rare herbs and flowers to synthesize a powerful sedative that can be administered via elephant gun to safely subdue a horror.” 

“The sky’s the limit. Or, perhaps, the abyss is bottomless? In this regard, the Guide is a great source book for more than just storyline ideas. Keepers can use the information within the Guide to create unique weapons, medicines, and toxins.”

Follow Up Letter from the Mysteriously Missing Dr. Luis Merlo

A few weeks ago we published the first letter Sandy received from Dr. Merlo claiming to have dissected and illustrated a compendium of bizarre creatures that to Sandy, resembled some of the imaginary works of H.P. Lovecraft. This correspondence led to a friendship and ultimately the publication of our latest book The Anatomical Guide to Lovecraftian Horrors.

Here is the next letter he received, which continues to lend credence to the authenticity of his work. Sadly, Dr. Merlo seems to have disappeared under mysterious circumstances so we can’t validate anything. 

“Dear Mr. Petersen,

Thank you for your quick reply. I must assure you, the ichor on that sample is perfectly safe, so there is no biological danger. Lack of sleep can be dangerous when dissecting novel species, and carelessness can have more dire consequences than some stains on my notes.

To answer your question, no, sadly I do not carry a camera around and have mostly disposed of portable electronics. When I began my research, I was not aware of how dangerous electromagnetic fields could be when performing certain operations. You see, light-detection is a very limited sensory modality, as it is restrained by the presence of detectable light.

Older, more complex organisms can detect radio waves, x-rays, or electromagnetic fields from vast distances. Needless to say, one of my first field experiments almost resulted in me dying because of the phone in my pocket. Added to this, cameras don’t work under certain … environmental conditions.

I know this is difficult to grasp, but I ask that you trust me. As soon as I know it is safe, I will post some tangible evidence that proves my claims. In the meantime, my corrected notes on the Byakhee lifecycle will be mailed to you by an assistant in the coming weeks. I am preparing for a journey to Asia and will probably be away for a month.
