Pretty sure if it was a drop from loot table, it would have been datamined. It has to be something else that starts it that cannot be datamined, or it's not even active in-game.
Nothing and Everything
Perhaps it will only drop if you have the Thunderfury achievement (or Thunderfury in inventory, or some thing along those lines...)?
"In today’s America, conservatives who actually want to conserve are as rare as liberals who actually want to liberate. The once-significant language of an earlier era has had the meaning sucked right out of it, the better to serve as camouflage for a kleptocratic feeding frenzy in which both establishment parties participate with equal abandon" (Taking a break from the criminal, incompetent liars at the NSA, to bring you the above political observation, from The Archdruid Report.)
has anyone considered the name? Hallowed instead of Blessed -- maybe Hallows End?
Has anyone tried tweeting any wowdevs or anyone for a hint or something? or even confirmation if it's available currently?
Nothing and Everything
the only clue I can pick up from is the description states these bindings are 'intended' to imprison the windlord. So someone out there has some kind of gripe with thunderaan and has these bindings to imprison him.. but this is too vague as I can't think of anyone lorewise who has a gripe with the newly resurrected windlord.
I recently made a thread in the general forums on battle.net asking if the dev's could simply confirm if it's possible to obtain. I'd really like at least that info so I know if I can stop wasting my time trying to figure this out. If you could go upvote it maybe they'll notice and respond!
So the Restless Tides mobs in the non-instanced eye of azshara you can't pick pocket, but the ones inside the instance you can.
Of course not, but Prat does keep whisper logs so "if only there was logs!" was a crappy excuse. Though to be fair, I don't recall if chat logging is enabled by default.
Seems like the most likely answer.
Anyway. Do other hidden appearances require spec-specific spell shenanigans like what we're assuming with Pick Pocket and Detect? They sound plausible enough, but at the same time it almost sounds too convoluted, especially compared to others that are simple as "kill a world boss". I'm starting to agree more with it being from unreleased raid or patch content, since surely someone would've found something by now. An intriguing mystery for sure!
I'd try the one's inside but they don't seem very "windy" to me anyway.
The NPC I'd like to try interacting with is this guy dread-captain-thedon

The only reason I really believe it's something to do with pick pocketing is because the Bindings of the Windlord are labeled in wowhead as "junk" which is a common thing we see when pick pocketing.
this is reminding me of that time pre-cata (i think) when suddenly everyone was super obsessed with some supposedly undiscovered (by anyone ever) quest in tanaris from a naga mob
also my brothers dads cousins boyfriend says that the thunderfury artifact appearance has something to do with sombra
"All I can tell you is that there are no known bugs and that all is working properly. "
This sentence leads me to believe its in the game now. Otherwise i dont think the gm would have replied with "all is working properly". It could be that i am wrong, but it would make that gm into the biggest a-hole on the planet. "its working properly because tis not activated yet TROLOLOLOL"
Edit:
Could it be a drop from the arcway or court of stars?
