I know there's a puzzle here, and I think I've found half the key... The link goes to a post made on November 17th, 2009 (17-11-09, to non-Americans, if I remember right), but I can't for the life of me find a post made by Fyr on the 13th of September, 2007 (which appears to be the day they registered?). Even if it's all a wild-goose chase put up by a random forumite, this puzzle begs to be solved. It has numbers and arrows and everything!
@proweler: You've just made so much make sense to me.
I'm no good with cryptography and word-puzzles, but this might be the other half of the key you're looking for.
Lest the above be thought adventitious,
13
9
7
It's a message relating to the Sermons: specifically, http://www.uesp.net/wiki/Lore:36_Lessons_of_Vivec,_Sermon_29 may be of use.
13: The Serpent
9: The Missing
7: The Sword at the Center
36
11
39
16. "The Acceptable Blasphemies" [12]-> "The Heavens" [379]
3 + 4 = 7 -> 39, /3 = 13 -> 36, /3 = 12, /3 = 4 -> 242
3. The Invisible Gate
+4. The Corners of the House of Troubles
=7. The Sword At The Center (39)
/3 = 13. The Serpent (36)
/3 = 12. The Heavens
/3 = 4. The Corners
(again (242)
3 -> 112, + 242 = 354 <- 22
So, Invisible Gate + House of Troubles = "354"
22. The Unknown (453)
Backwards*
The unknown becoming known, perhaps? Or referring to something entering/exiting the "Invisible Gate"?9 -> 11, x 2 = 22, /2 = 11 ...
9. The Missing (11)
x2 = 22. The Unknown,
/2 = 11. The Number of the Master (102)
So...
17. The Hurling Disk
11. The Number of the Master
9. The Missing
I operate on a timetable that spans years.
Noting that the "PERYITE" verse was posted on the above date.
Also, the Treasure Wood should enter into this.
My gut tells me the "Treasured Wood" is a reference to Valenwood and the discussions surrounding the Thalmor kinda support this
(circumstantially), but I can't find any actual reference to Valenwood, or indeed anything, as literally the "Treasured Wood."

Honestly, I have no idea what to decipher from all that, but I hope it's useful to someone.
EDIT: I actually went looking for "379" in the UESP "timeline" page first, as it seemed more like a date (as in 3E 379). Ended up on Sermon 29 by accident, and found it all matched up.
