I'm really surprised at your lack of google skills in one major area and one minor one.
I told someone that the creatures that attacks dearly were Deep Ones but it was not posted here. Those are a major Mythos element.
Hut the big one was STARING at you right in the face. I even helped you in a write up.
The Diary of Jacob Typer
Now, which Typer founded the family estate in the writeup?
Alonzo.
The Diary of Alonzo Typer -
H.P. Lovecraft's "The Diary of Alonzo Typer"
An actual story by HP Lovecraft
A simple google for Typer and Alonzo would have brought it up.
