In “The Call of Cthulhu”, by H.P. Lovecraft, the tentacle man himself is able to make people all around the world have horrible lucid dreams of R’lyeh and his eternal resting place. These dreams basically transport the individual’s consciousness to that place, letting them not only be aware of their surroundings but also somewhat interact with them.
This ability reminded me very much of the way mages perceive dreams in the ssss universe, able to interact with them and move through them at will. And then I remembered how Reynir’s fylgja has a tendency to drag its mage around the dream world to strange and mysterious places.
So what would Reynir think if one day his trusted companion suddenly decided to run off towards a mysterious new location, like it was answering a call directed to it, prompting its master to desperately run after it? How would he react to the cyclopean structures, inscribed with eldritch creatures and weird runes, that he would inevitably see his dog make its way through? What would he think of the monstrous abomination at which his dog would eventually obediently stop, prompting him to stare in horror at the titanic beast?
And most importantly, how would he react when he would realize that the monstrosity, which seemed impossible yet all too real, was staring right back at him?
