I started this thread on reddit but would love to get more input.
This could be absolutely nothing, but it seems too related to be random bits thrown on a page.
The page in question: http://i.imgur.com/L61tBU6.jpg
Now, it's possible that the devs said "Throw some history stuff on the pages and let's wrap it up already." but in doing a bit of digging I think it may be more than that.
I originally thought the top right was a misspelling of "Croatian" but I can't imagine Lara (or the devs) would make such a mistake. So I did a bit of Googling and, among other uses of the word Croatoan, found a lot about Roanoke Colony. For those unfamiliar with it Roanoke Colony, was an English settlement in what is now North Carolina in the late 1500s. It mysteriously disappeared and there was no sign of "foul play," in fact the colonists had clearly deliberately dismantled their colony and simply vanished, leaving only the word "Croatoan" carved into a post. Roanoke is now known as the Lost Colony.
Now, there are other uses of the word Croatoan, such as a Native American tribe or an island (more of a reef, really) which are both in the same area but the next bit is why I believe Roanoke was what was being referenced.
On the left page we have, among other things, a note paper with Cyrillic writing. Redditor milancheee let me know that the writing is actually English but just using the Cyrillic alphabet and translated it as:
Eight have origin
Lost deel village
The lost village bit combined with the "Croatoan" is why I believe we are referring to Roanoke.
Below that we see a bit of paper with the number and roman numeral for 3 on it. This is what actually got me looking at this stuff in the first place. Redditor SomewhatSpecial asked about Trinity, a mysterious organization you learn very little about and questions are left unanswered. All we seem to know comes from two files:
Number 1 http://i.imgur.com/qUsxUbR.jpg
Number 2 http://i.imgur.com/kci0CP8.jpg

Lara finding this reference to Trinity on the island may have her seeking out more about them/it. I believe that the presence of the 3 and III with the question mark could mean what we're seeing on the pages are related to Lara's search for more information about Trinity.
The bottom of the original screenshot is German. Redditor darthbiki reports that it is "Sie ist der Schlüssel" meaning "She is the key".
So here are the general elements of the page:
1: Top Left, note with Cyrillic. Translation:
Eight have origin
Lost deel village
May refer to Roanoke. I do not know the significance of "eight have origin."
2: Behind the note you can see a drawing of what could be a spear, arrow, window, etc.
3: Note with 3 and III? - Could be referring to Trinity
4: Drawing of some cliffs with what appears to be a cave circled in red. The drawing is taken from a book of some sort, indicated by the Figure: Etching underneath.
5: German - She is the key.
6: Top right is the word Croatoan with an arrow pointing towards a spot on the map below. Croatoan may refer to Roanoke.
7: The map is faded and it is hard to compare it to any area maps I've looked up of the area around Roanoke or Hatteras Island, historically called Croatoan. There are red lines drawn, some of which appear to follow a border and/or river. Interestingly the arrow does not point to the same location that is marked with the x on teh map but to a separate spot.
8: Blood stained paper saying _runter. I can't make out the first letter clearly but, if in English, the logical word would be grunter. However the first letter doesn't appear to be one used in the English alphabet so this may be in an alphabet like Cyrillic that shares some characters with English.
9: The writing at the bottom appears to be in Cyrillic or an alphabet that shares characters with it, but due to the font my layman eyes can't determine a way to read it.
Furthermore I was searching for a map to compare to the faded map in her journal and found this map of the area surrounding Roanoke:http://i.imgur.com/DHA2Fsi.gif
Note that Roanoke is located at Trinety Harbor. Could be something.
So there you have it, there's everything I know. Any other contributors care to share any knowledge they can put forward, or any fun fan theories? Anyone able to read the (possibly Cyrillic) writing on the bottom of the right page?
