So, first and foremost, i am talking more about speculation than canon, but some of the things are facts.
This thread is for those of us intersted in understanding and make some stuff clearer about these old beings, yet of course, Blizzard is with the upper hand, and they can invent whatever they want about whatever they want.
TLDR:
Does it seem to you that it might be the Old Gods, and not the Burning Legion that is the main threat to azaroth as we have been told to believe?
So lets start with some facts:
1. The Old Gods have been described as even more powerfull than Titans, and that for the titans to "win" any fight against the Old ones, will be hard and must be brought by several Titans.
2. Currently, there are 4 known Old Gods, and their minions differ (somewhat) from one another.
3. It is also known that they do not get along so much, but they do tend to help each other influence the "Lesser beings" and coerce them into doing their bidding for the sake of their own betterment (Allthough its not proven, i believe that more than one of them has corrupted Deathwing and his Demon Soul...)
Now i will plunge into somewhat speculative waters...
1. The Old Gods, Cannot die by mortal means, though we do have one "dead" Old God on Pandaland, his shadow alone was enough to corrupt the land and cause harm.
I believe the "dead" current Old Gods are just playing dead untill such a time as they see fit to come back once again.
2. They seem to have influenced every major debacle that ever became a threat to Azaroth, as a fact, we have Deathwing and the Nightmare to testify to that...
I believe that Ner'zul managed all he did by the influence of Yogg-Saron, and Arthas taking over also seems rather chaotic Old Godsie style.
I actually believe that even good old Sargeras and Galakrond were both influenced by them. If anyone has the power to corrupt a Titan... And Galakrond is pretty obviouse i think.... with all those extra appendages, and Undead army.
3. We dont know yet exactly how many there are, or where they are being held, or if there are any free ones in some dark reasese of the universe.
What we can say with absolute certainty is that they are strong, and perhapse... Unbeatable?
Do you guys thing its possible that Blizzard Planned for these monsters to be the main threat while holding to the shados?
Take into acount, that in every single expansion we get just a little bit of Old God... Or more than a little... untill this WOD... Doesnt seem right...
-Vanilla, an actuall Old God comes to Azaroth.
-TBC, some arrakoa try to summon some Old being looking like C'Thun.
-WoTLK, we see Yogg-Saron.
-Catclysm, the whole expansio is a huge tribute to the Old ones.
-MoP, the Sha and a Heart.
-*WoD, Cho'gall? Again?
And another speculation of mine, is how many Old Gods are infact imprisoned on Azaroth.
Since the locations of the 3 Famous ones Are knowen, and we can assume that Mr. N'Zoth is hidden under the Maelstorm, under the sea somewhere, i think that there are 3 more, and that their imprissonment is as follows:
One hidden beneath Tirisfall Glades.
One hidden beneath The Dark Portal.
And the last... Hidden beneath Mount Hyjal... (imagine a spooky tune).
To me it makes the most sense, and if i have time, ill make a picture of aome sort.
Remember that the land that the Old Ones were imprisoned beneath was not yet Sundered.
Well, Lore loving friends.... What do you think?
