ARG:Undoing

This page contains spoilers about the Heartbound ARG. If you want to solve the puzzle yourself, avoid reading this article.

Undoing was found by solving the Lunacy puzzle, which led us to the page https://gopiratesoftware.com/games/Heartbound/CORE_DUMP/MEMORY_ALPHA/CRASH_LOG/BOOT_RECORD/DEEP_THOUGHT/2140425/U4042/HEAPCHK/U4043/RESISTOR_TWISTER/FINAL_MACHINE/MOONSIDE/

The page has the Artifact's eye, and the following on the source code:

<!-- You are everyone you've ever met. -->
<!-- Mothers. -->
<!-- Fathers. -->
<!-- Sons. -->
<!-- Daughters. -->
<!-- Friends. -->
<!-- Enemies. -->
<!-- Hopes. -->
<!-- Dreams. -->
<!-- Fear. -->
<!-- Curiosity. -->
<!-- A singularity. -->
<!-- A finite point in space. -->
<!-- Memories of the masses. -->
<!-- Your experience is the key. -->
<!-- Everything Matters. -->

"Lore"

This is the final puzzle of Chapter 6 of the ARG, which started by dumping OScar's core. We are deep within his data, and we might find some secrets about the nature of Heartbound:

You are everyone you've ever met. Mothers. Fathers. Sons. Daughters. Friends. Enemies. Hopes. Dreams. Fear. Curiosity. A singularity. A finite point in space. Memories of the masses. Your experience is the key. Everything Matters.

The text suggests that Lore is the combination of the memories of many, which ties back to the first page of the ARG, that said:

This body is an illusion.
This mind is a collective.

Puzzle

At the end of the current page, we also have another text encoded with the Vigenère cipher (the same cipher used on the previous puzzle):

LAYZLSKPVJXERFPYXWFMJRBRHZ
FAWEYGBICYFLFMALUJOIXICVQK
MYUKYLLZTTLDUQMZAASKWFRAIQ
WXSQYVOFUSYWTJPQINEVQJMFUA
SLWMSBJMPOMMRXQPTTOBTYAUDV
AKQNPQYEZJHNRAKJEHAAQPQYDS
LR/WIJBHNELQYVZRA/FVDUX

One thing that stands out on the ciphered text is that there are two slashes on the last line. The clues above the text are are "Your experience is the key" and "Everything Matters".

So in order to find the key to decipher the encoded text, we need to somehow use all sentences before it. What we need to do is to get all capital letters of them, in order to form the key YMFSDFEHDFCAAMYEM.

Solution

By using the key to decode the cipher-text, we get:

NOTHINGISEVERTRULYTHROWNAW
AYWEMIXWEMATCHWEREMIXWEREM
ATCHTHEWORLDISINCONSTANTFL
UXSEARCHINGTOFINDLEVELITWO
NTTHOUGHNOMATTERHOWYOUTRYT
AKEPLEASUREINTHECHAOSLEARN
TO/RECYCLELEARNTO/ADAPT

Now let's add spaces and punctuation, to make it more readable:

Nothing is ever truly thrown away. We mix, we match, we remix, we rematch. The world is in constant flux, searching to find level. It won't, though, no matter how you try. Take pleasure in the chaos. Learn to /recycle. Learn to /adapt.

The text probably links to what we discovered at Floor 0 of The Tower, where we found that its characters are made from memories, and recycled as necessary.

The text's slashes are before the words "recycle" and "adapt". Those slashes represent the addresses of the next pages, so those words are what we need to add to the URL in order to get to the next pages:

Those two pages bring us to the first puzzle of Chapter 7 of the ARG: Stopwatch.
