Post lore/secret stuff here
Here's what I've found so far:

1. The morse code says CAL
2. The note page is a Vigenere cipher and decodes to this:

"the lunarcore project is X large-scale research program based on X discovery made in 1986 related to the unique properties of lunarore. this element has the ability to influence the subconscious and opens up new perspectives in the field of knowledge transfer between people. the lunarcore project aims to develop a method for creating a full-fledged core capable of transferring information and knowledge from one person to another.

the main goal of the lunarcore project is to explore and maximize the potential of lunarore to develop an innovative method of knowledge and information transfer. the creation of a full-fledged core capable of interacting with the subconscious level of a person can lead to revolutionary changes in the field of education, science and interpersonal communication.

the direction of development of the lunarcore project will remain strictly confidential, and access to information will be provided only for the purpose of promoting the project and ensuring its successful implementation.

with respect,

??????
lead engimeer of infinity
lunarcore project"


The typo of engineer could be a normal typo or something else, I'm not sure
That big ball room thing could also be this "Lunarcore" thing they're talking about

3. There are slabs hidden throughout the map that you put inside the Lunarcore, here are there locations

- Up the parking lot stairs in the corner
- On the parking lot roof behind the wood
- Inside one of the open red containers in the water
- Behind a container in one of the maps corners (Facing the core, it's the southeast side)
- In the tall, derelict building

4. There are certain areas that have indents in them where you can insert a tablet. There are images listed in the comments about said locations, putting in the tablets in the right order reveal qr codes that have these links

5. The R was encoded in the Vigenere cipher again, so here is the result after decoding:

"hi i have some bad news for you.

i'm not the one who left the previous notes. i'm just like you. a copy without knowledge and
memory. i found the last artifact to make a final note and report very unpleasant information.
as i read from the documents found, the experiment with lunarcore was conducted sometime
in the 1990s.

however, i found the last computer that was still working. judging by the date... more than 120
years have passed since the appearance of these notes. and i do not know after how many
repeated activations of lunarcore you will find these notes...

this place is powered by lunar energy, so there will be enough electricity for another two
centuries.

as for the tasks... i do not know what to do next, except to activate lunarcore again. i'm sorry,
but that's all i can do. apparently, our destiny is to wander around this place, passing the soul
to our copies, for many more years..."

It already seems like we have a majority of the puzzle pieces together, although we're still missing that one piece: the code to the Lunarcore
Post any of your findings here

We've solved it (probably), the code for the lunarcore is 2579
