There are some things I remember from DHMIS I think we should have been paying more attention to as theorists. Such as:
The whole "DHMIS Phone number" Thing could have some interesting lore to it. I only remember one recording of it, In which steak guy picks up and says "Hello", And then says "Rude" And hangs up. I feel like this could have some meaning to it.
Roy's confirmed last name is "Gribbleston", And a "Gribble" Refers to a type of bug.
I very distinctly remember this recording in which they called the number, And rather than get a character they heard indescribable screeching. The screeches seemed to be attempting to communicate with them, But were unintelligable.
Finally, My personal favorite since it clearly has a lore meaning, "The Silly Sad Duck", Just google it, It's one of the most damned interesting things I've ever seen and yet nobody seems to remember.
