Battle for K'tanth
Xal'atath makes several other remarks regarding the Broken Shore and its connection to the Old Gods. The dagger claims that the Tomb of Sargeras pales in comparison to the grandeur of what stood there long ago. It explains that Thal'dranath was always a place of power, and that Aegwynn was drawn there, as were the elves, the trolls, and something else before them, likely the Old Gods. Furthermore, Xal'atath claims that the land had not seen "such carnage" since the Battle for K'tanth, which occurred "long ago", and that it was "here" in ages past that the God of the Deep lost a great battle to the God of Seven Heads, though the defeat ultimately worked in N'Zoth's favor. Thus, it can be speculated that the battle between N'Zoth and Y'Shaarj was fought over this place of power and the great edifice that stood there long ago that might've been named K'tanth, or alternatively, what was situated beneath it.
- The edifice might have been destroyed during this battle, by the elemental armies that brought down the temples of the Old Gods, or by the titan-forged who destroyed the Black Empire.
