The Observer

The Observer also known as:The Eyes,Black Rook,The Sentinel. Is a malevolent and mysterious entity that is following Noah Maxwell. The Observer has similar abilities like Slender Man. Like manipulating time and space. He connects to Noah by cryptic packages and letters,and videos that usually are black and white with shaky texts.

The Observer serves under the Slender Man, whom he refers to as his "keeper". He states that he fears him, and that this fear is what compels him to do his bidding. He also refers to himself as merely a tool for the Slender Man to use and dispose of once his purpose has been fulfilled.

In November 10,2012, Noah tweeted photos of a letter he received from the observer saying,"I'm so sorry Noah, They're too powerful, Kill me I'm only a tool, He can't use my body then, Kill me, Kill me, Kill me'." Noah claimed that the writing style was from a friend named Kevin, confirming that Kevin is the observers vessel.
