I am new to Reddit, and this was the best place I could think of for posting this, but I was looking through the Night Mind horror index this morning, and I found an ARG called ArrowSmart. After looking around for a bit, I discovered that on the very first page you land on, the source code has hexadecimal that leads to a page called Echo.html. On there, another page called Personality files can be found. It has a few cool references on it, but I have a feeling that might hold our next big clue.

Here is the link to the index; it is the second one down in the index, right below the Cup O' Joe Archives. https://www.nightmind.info/horrorproj

Just thought that it was interesting and wanted to share my leads with everyone.
