Faceless Ones are often misconstrued as being directly created by (originally) Yogg-Saron and then also N'Zoth. However, neither of these are true. It seems that each and every Old God has displayed reliance on Faceless Ones in carrying out their greater schemes, including the creation of lesser races such as the Qiraji, Naga, and Sha. N'Zoth's Faceless Ones do tend to have a more aquatic appearance, but this is likely due to N'Zoth being chained under the sea and the Faceless Ones evolved over time.
Additionally, murals of Faceless Ones are seen in countless locations including raids and dungeons associated to N'Zoth, Yogg-Saron, and Y'Shaarj. C'Thun has a huge following of Faceless Ones in the Twilight Highlands and Bastion of Twilight, etc.
So, who are they? They are clearly a very developed race with different roles manifesting in different physicalities - casters, generals, "grunts", etc. They have their own language and their own hierarchy. So, where do they come from? Are they formed from the blood of the Old Gods? If so, who is responsible for which one? Furthermore, when we discuss the Faceless Army headed by Warlord Zon'ozz, etc - why would armies of the same race attack each other in this fashion? Further still, if the Big 3 (C'thun, Yogg-Saron, and N'Zoth) were supposed to be in cahoots, then why would Zon'ozz's army fight against the others?
