BEN can be referenced almost anywhere on Youtube, 4chan, Tumblr, Deviantart, and anything else. It is a world wide story known by many. He is the one who torments Alex and Link. He is also the one who communicates Alex over the game and a website known as Cleverbot, I suggest checking it out and trying to make a conversation. For those of you with an Apple divice, download it. That version seems to stay more focused on the topic you want.
To be more informed, check out the story. It's found here! But be sure to have plenty of spare time if you want to get it done in a day, it's a long story. Also, don't skip the videos or any parts of it because you'll be confused.
