So I am going to preface this by saying I am not a huge lore buff, so I might recall some details incorrectly. However, this idea popped into my head and I enjoyed the thought so much I thought why not share it. And on the extremely rare chance I am even partially correct, atleast I get bragging rights to say I came with the idea first (atleast I couldn't find any discussions for this inane idea anyways). So with that outta the way, here is my theory.
While exploring the new map extension of Bjora I noticed that the devs went into the effort of implementing a Claw of Jormag that flies around the sky and roaring occasionally. You don't seem to be able to interact with it as far as I can tell, but it is a really nice feature to put in the environment. It was then it got me thinking, this map now not only has a Claw of Jormag, but Drakkar throughout the story is repeatable refer to as its "mouthpiece". Interesting phrasing. I guess you could say..... Drakkar is its voice....a "Voice" of Jormag. I think you see what I am getting at.
For some reason or other Jormag has both a Voice and a Claw. Similar to that of the Kodan and their belief system with Koda. Isn't it also interesting that there is SUCH an emphasis on the kodan whenever Jormag is involved. It is the kodan who are holding the line in Bitterfrost frontier, it is they who shut themselves out from the rest of the world in Still Waters Speaking to prevent the whispers from spreading father. Now of course an easy explanation is because of course they are the only ones you would interact this far up north-no other race is this far north since the norn fled. And yet, during the meta event on the new map Jormag says it themselves.....they are trying to help the kodan and the norn. Why so specific? Why not just say "I am trying to help you all." Why specifically call out the kodan. It almost as if they have a deeper connection with one another wink wink
Another thing I would like to point out, is the tendency for the Voice of Koda to go ....insane during their duties. Recall if you will from vanilla gw2 maps like Frostgourge Sound where you have events like "passifying"(beating the kitten out of) the Voice at one of their floating sanctuaries when they go beserk. Hell I think even one of the dungeons, Honor the Waves, even touches on that as a plot point where you attempt to rescue the Voice only to find out later they've been turned by Jormag. So it seems it is pretty common for the Voice of Koda to eventually go insane upon listening to it after awhile. Know who also makes you go insane when you listen to it's whispers? That's right...Jormag. Hell in this patch alone we have not one but TWO examples of this happening. The first we hear about Ushers-In-Spring who was the Voice of Still Waters Speaking who attempted to listen to the whispers and was turned. The second being the norn scholar you follow while doing the achievement "A Hunger for Knowledge" where we find them dead after mistakenly listening to Jormag's voice because they thought it was a friend's. It seems curious how Jormag and Koda seems so alike in how they operate doesn't it. Both how their own Voice and Claw, both whisper knowledge and guidance, and both will eventually make you crazed by their whispers.
So I know what you are thinking, no-they cannot be the same, surely the kodan themselves would be able to tell the difference between Koda speaking to them and Jormag right? Once again this patch explains it very well. That norn scholar I mentioned earlier, recall how I said that the reason they died was cause they mistakenly thought the voice they were listening to was their friend's voice. So we know that Jormag can change their voice to sound like basically ....anyone they want. A friend..... a family member... maybe even Koda itself?
So my theory is simply that either Jormag is essentially Koda, or at the very least highly connected and intertwined with Koda (maybe Koda is a piece of Jormag like (spoilers the Whisper of Jormag end spoilers). There are just too many similarities between the two for it to just to be a coincidence. Now I am going to leave the post here for now cause I actually have to go to work. XD Hope you enjoy reading my stupid idea.
