(you should know who this is considering you searched them but if you don't know Aka Manah or also known as Akoman or Akvan and they are from Zoroastrianism culture they do not have a gender but they are mostly depicted as male.)
Now back to the story
You are an avid book collector and when you're parents died you were already living in your house but you had inheritance and considering your there only child all the inheritance went to you although you decided to give the stuff the didn't have sentimental value to charity but since you loved to collect books you kept their books and put them in your collection up in the attic although one booked that cought your interest the book seemed to be made out of some sort of leather but it didn't seem like animal leather but you don't want to dwell on the thought especially because of your parents death but after a month and some help from friends you got over your parents death.
But when you finally get back to your normal life you realize that the "leather" book seemed to be downstairs instead of the attic out of nowhere and this kept happening sometimes even showing up on your bed and eventually you decided to open and when you look inside you find it seems to be a Necronomicon which would line up with the fake "leather" cover for the book although well going through the pages you get a paper cut your blood falling onto the page it happens to be on the page for Aka Manah and you see a Pentagon forming on the ground and a large red spiral comes up from the floor as he slowly rises from the ground now standing In front of you his red eyes staring down at you and he speaks his voice deep and menacing.
Aka Manah: Why do you dare summon me mortal!
