"Sage"

Human Sage
According to the "Save Alan Richardson" forums, "Sage" (it is unkown wehther or not this was his actual name) was Alan's former room mate at their college. Through the forum some of his "findings" were posted but as players read more of his topics it's revealed that "Human" Sage is most likely deceased. His account name has been taken over and the entity that took over is referred to as Sage. This also confirms that it's likely that this entity is in fact not "BEN". It's stated that Sage was able to communicate with Alan through the Song of Healing but Alan could only respond in Binary. There's no records of Human Sages' conversations with Alan. What he thought was BEN would immediately answer Human Sage's communications with the Song of Unhealing. Which is most likely what lead him to believe it was BEN.

Entity Sage
This seems to be some most likely insane soul or spirit that takes possession of electronic devices. He seemed throughout ARC 1 to have the same characteristics as BEN but players discovered the strong difference between BEN and Sage. Sage seems to have alot of characteristics as someone with split-personality disorder. Much like the personality of Majora in the Legend of Zelda title. He seems to toy around with the players, persistently taunting them with the infamous "HeeHeeHee. His native language seems to be Hexidecimal, if thats even possible. In posts he's also seemed to speak Italian an Native Hylian. It's been confirmed that when anything is posted in Binary it's Alan breaking through whatever prison he's in to leak information to players. Which seems to anger Sage. Sage also taunts with hints which are seemed to insult players for not being able to figure out specific puzzles. Currently Sage's role in the ARG is to apparently stray players in different directions to allow them to not find out "The Truth" according to "Only One Will Die". His conversations with his "Leader" are what implies his split-personality. It seems he has three forms of existence. Threatening, Normal, and Insane. It is unknown why but again, it shows many similiar traits to Majora.
