Sounds like I implied the appearance is tied to an NPC, huh? Well that's because the best lead I have so far implies that it is.
Now, it's flavor text says: "Fed by the steady settling energy of Icecrown Citadel, this crude and brutal weapon could easily be fashioned into an instrument of death."
A lot of people have assumed this means it's in or around Icecrown Citadel, the latter (around ICC) may be true. But I believe the hint is moreso in the middle and end.
If you look at the currently shown artifact appearances for the unholy artifact, which is appropriately named Apocalypse for what I'm about to suggest, you'll see that each appearance besides the initial one is linked to an aspect of the Four Horsemen of the Apocalypse.
Faminebearer is linked to Famine.
Herald of Pestilence is linked to Pestilence.
Unholy War is linked to War.
That leaves Death. Notice above the flavor text's end: "instrument of death."
There are, as we know, Four Horsemen in WoW. The original ones were Lady Blaumeux, Highlord Mograine (Replaced in WotLK by Baron Rivendare), Sir Zeliek, and Thane Korth'azz.
Noticed I bolded Thane Korth'azz. Well, it's widely accepted that Thane Korth'azz is the Pale Horseman - The Horseman of Death.
Another interesting thing to note is that the flavor text says: "this crude and brutal weapon could easily be fashioned"
This implies that the item is already a weapon. Interestingly, Thane Korth'azz's weapon in Naxxramas is a bone hammer - crude and brutal.
Now I've gone into Naxxramas and killed the Four Horsemen while using Apocalypse, and it didn't give me the appearance. But that's not what I believe it's tied to, now.
In Legion, a new model for Thane Korth'azz was datamined. It's unknown if this new Korth'azz NPC is in-game, but if he is, I believe he drops The Bonereaper's Hook.
My ideas are that if he's in-game in the Broken Isles, he's either somewhere below Acherus in some way, or in Stormheim, Helheim, Maw of Souls, Halls of Valor, or The Broken Shore.
If he's elsewhere, he's in Northrend or Eastern Plaguelands.
I'll check this out further when I have time, I suggest other unholy DK's do the same.
