This is, perhaps more “understand the story being told” than “decipher the clues”, but a lot of the stuff in that pastebin doc seems to reference the transition from TSW to SWL.
“And yet, there is eleven where once there was ten.”
Seems to be talking about how it now takes 11 shards to open the Gatekeeper and/or the induction of the Tech Golem as being on equal to the rest (unlike the past anniversary events)
“Its programming dictates the path, but its path is not there. Where did it go? It is inscribed in its very existence.”
A lot of the old branches of Agartha have been removed in favor of the jump pads but there are still custodians who wander the branches down below.
“n the end, two branches sprawl before it, and it does not know which to take. They, like it, once had purpose.”
Recently re-added branches for the anniversary event include a hub like location with two branches that come off it. This area used to be (or is very similar to) the branches that used to hold the Elite and Nightmare dungeon portals.
“And so Kapsu Nasiru waits.”
Kapsu Nasiru was a silver golem that spawned in Fusang projects, a pvp area, during the old anniversary event. Much of the story given there appears to relate to the silver/lunar golem.
Not sure what is going on with the clever raven scouting above and the wise hare hunting below might be.
