Woah an ImpendingHorizon thread! I came on here to look for some new series and thought I would comment about this particular one here. My friend talks to the creator on tumblr (I think her name is Taylor) and said that she told him that the main antagonist is not the slenderman? I thought that the Messengers were actually being controlled by him at first, like TribeTwelve's Collective, but apparently it's something completely different. I'm pretty interested to find out who/what it is.
