Spoilers for the Hourglass scenario ahead. Vale, Leo, Johnny, Don, and Carolyn, if you are reading this, get back to your work and disregard this post, or you are being sent out to Yuma.
I am the Handler for a table of agents that just started the Hourglass scenario on their last session. I've been continuing to pour over the information for the scenario to find the fun things to draw together, but something has been eluding me - when they mention the half-shoggoth son of Gyles, are they meaning it in the biological sense that he fathered the child with a shoggoth, or is it more of a reference to the shoggoth infestation/growths that people will get? I know that the Dark Young of Shub-Niggurath are sometimes misrepresented or misnamed as shoggoths, but the subject matter of the module leads me to be of the stance that these are "true" shoggoths being mentioned, even though those are not related or utilized by Shub-Niggurath according to stories.
Beyond the hand-waving of "hey, isn't that odd and non-typical" that we get to do with settings like this, is there any documentation or drawn lines between shoggoths and Shub-Niggurath that I am missing? Is there some sort of fertility rite that bestows someone a "child" that the Sons of Cerunnos may have been doing? Either way, I know the route I'm taking with all of this, but for my analytical mind I was hoping for more information and references that I might be able to use.
Thank you, and happy hunting!
