TribeTwelve is a video series with ARG elements set in the Slender Man Mythos. Originally started as an homage to Marble Hornets, TribeTwelve soon branched out and became a series of it own. In addition to the Slender Man a new antagonist known as the Observer was introduced, bringing a new level of intrigue along with him. From early on, the series was noted for its special effects and editing, which surpassed anything else available at the time. TribeTwelve is considered to be one of the "big three" video series, alongside Marble Hornets and EverymanHYBRID.


Noah Maxwell created a YouTube channel for the purpose of showcasing his project on The Twelve Tribes of Israel. When the project was cancelled, Noah decided to use the channel to upload the footage he had filmed with his cousin, Milo Asher, in May of 2008. On May 28, 2010, Milo's mother, Mary Asher, had called Noah to inform him of his cousin's death. Milo, who Noah had not been in contact with for the past two years, had died of a drug overdose in his bedroom.

After locating the tapes, Noah began uploading footage and soon realized that Milo had been behaving oddly at the time. In addition, a tall figure appeared in the background of some of the videos, although Noah had not noticed at the time of filming them. Several months after he began uploading the footage, a mysterious entity known as the Observer began sending Noah cryptic messages and uploading videos to his channel. Over time, the Observer began to reveal his true identity; he was a member of the Collective, a group of supernatural entities in the service of the Slender Man. What he desired was simple, the Nazi journal in the possession of Noah's grandfather, Karl, which may contan the secrets needed for the Slender Man's defeat.
