About The Unknowable: Darkland
"The Unknowable: Darkland" explores the complex characters and supernatural forces behind the Darkland amusement park. The mysterious disappearance of a local teen, Tammy Gillis, reignites the obsession of Atticus Fairbanks, a private investigator and disgraced former police detective. Fairbanks’ search for answers will unearth not only the truth of what happened to Tammy, but secrets about cult leader Dexter Venito, who built the Dark Lands amusement park, and his wife Theodosia Birchwood, who went missing 25 years prior.
