ShaunaTheDead

It’s not exactly “unrecognized” because it’s fairly popular, but From – yes, that’s the name, and yes, it makes it very difficult to search for.

It’s pretty highly rated, horror/mystery show. It’s a lot like Lost except more horror less mystery. It even stars Harold Perrineau who played Michael in Lost.

The concepts and monsters are very scary and/or creepy. It gives me a Dead by Daylight “The Entity” and “The Entity’s Realm” vibe if you’re familiar with the game.

It matches for non-primes and doesn’t match for primes.
