This page contains spoilers about the Heartbound ARG. If you want to solve the puzzle yourself, avoid reading this article.
This page contains the second two sets of Guardian Glyphs. Continuing the pattern set by the first level, the puzzle itself is in the source code of the web page. Our hint this time is "Signal".
In the page's source you will see:
<div class="Signal"> <!-- *%%$*$%*%*$****$%%%$%%%$***$*$%***$%%%$%$**** --> </div> <!-- Keep your head down and keep moving. --> <!-- This is the way it should be. -->
This is a hint as to what cipher to use: A common method of sending signals is Morse code.
The ciphertext is encoded with Morse Code. However, a trick has been played. This message uses "*" for dot, "%" for dash, and "$" as a letter/word separator.
First, decode the ciphertext to ".-- . -.-. .... --- --- ... . -... --- - ....", then decode that to "WECHOOSEBOTH". Now add the results to the address bar in your web browser, and the result will be the Guardian page.
Guardian Glyphs Translation
The symbols in the web page are Guardian Glyphs.
We are closer to the source now
Memory is the key to this mind
