I know there are several Old Gods of Azeroth, and while we don’t even know about all of them there are a few that we’ve gone up against as heroes. To me, none is greater than Yogg-Saron.
I remember when the trailer launched. Man, did I have goosebumps. The Lich King was always the end boss of the expansion, but Yogg-Saron played a fine secondary threat. As the developers themselves have said, though, it’s too bad the connection between the two could not have been better established in the game. Heck, it took me long enough to draw the connection between the Old God and Saronite (for which I felt silly). “Yoggie” as I called him, was to the Lich King what Kil’jaeden was to Illidan. Granted, their focus and introduction were very different circumstances.
What intrigued me more about Yogg-Saron was the historical aspect. It’s a fact the guardians in Ulduar were supposed to keep watch on him, but he unraveled that pretty well beginning with Loken. Along those lines, it’s believed the Old God was responsible for several major incidents including King Llane killing Garona Halforcen and the corruption of Vordrassil. The theory on that one is that the trees roots grew too deep and got too close to Yogg-Saron’s prison. Evidence to support this is the Furbolgs that moved into the long deserted tree and went nuts in the process.
Yogg-Saron comes off as a dormant threat until Ulduar. But the truth is, it feels more like the Old God just sat and waited, biding time and manipulating where it could so be done. Even the Scourge curse his name. When you’re more evil than the bad guys, that tells you more than enough.
