Guild Wars 2

That’s pretty much all we know. Snoop around old topics, there are at least 5 on the same subject…

1) Kralkatorrik was never “known as earth” – initially he was thought to twist nature into nightmares, per The Movement of the World, but at the same time he was always called the desert dragon and he had concept art titled “water dragon” – but he was never an “earth dragon.”

2) Nothing really happened to the DSD. It’s just not active around continental Tyria, and since those in said continental Tyria are cut off with the rest of the world, they know little to nothing about it. Though earlier today I updated the deep sea dragon’s wiki page to include all information since release, since that was lacking. Basically since release all we got is confirmation of Elder Dragon influences forcing quaggans, krait, and karka out of the Unending Ocean depths (and supposedly largos too, since they come from the Unending Ocena depths and both they and quaggan talk about horrors/scary things there (words being used by the respective race)).

3) You can probably search Mordremoth/Modramoth (Mordramoth was a mispelling of the name which was first how it was mentioned). As Mystic said, there’s a lot of topics on it already. On this forum, Mordremoth is often used by folks attempting to connect the Pale Tree to being an Elder Dragon’s champion. This, however, doesn’t work despite common belief (though there is evidence to support the possibility that at least some parts of the Nightmare/Nightmare Court are tied to Mordremoth – but not the Pale Tree, Dream of Dreams, or sylvari race as a whole).

Some of the pre-existing threads, all gleaned from searching Mordremoth or Mordramoth, from newest to oldest:

Warning: The threads speculating the Pale Tree is an ED/ED champion may sound reasonable, but they ignore a lot of important information.

If you want just the facts, well, the wiki’s pretty much all the pure cold hard facts we get. If you want an objective (or as best as a single human who fervently hates a specific popular hypothesis that’s being debunked in his research can provide) view of all possibilities (though outdated), my research is what I’d suggest (note: I’m not saying its better or more accurate, just that when I try to research, I try to be as objective as possible, and as I’ve said, most of the threads relating the Pale Tree to the sixth ED ignore some important facts – same with those who try to link the Six Gods with the six Elder Dragons).

If you hang out around these lore forums, you will find a lot of interesting stuff along these lines

We pretty much know that there either is or was (probably still is) a sixth Elder Dragon in addition to ‘Bubbles’, though most of Tyria doesn’t know it yet I don’t think (heck, most of them don’t know about Bubbles). Everything else is informed speculation though. It seems ArenaNet know they have a dedicated lore community and like to drop teasers here and there for us to find :P

Personally, I think Mordremoth is awake, and woke up roughly 50 years before Jormag/after Eye of the North. Why? Primordus woke up at that time so reasonably speaking, another shouldn’t have. The thing to take note of however is that Primordus was pushed back roughly 50 years. I don’t think the other Elder Dragons relied on Primordus waking up first, and at least three Elder Dragons had active/semi-active champions in the world (possibly four or five, depending on Rotscale’s and Kuunavang’s relation to the Elder Dragons given their comparison to being like Glint) – The Great Destroyer of Primordus, Drakkar/Nornbear of Jormag, and Glint of Kralkatorrik (though whether Kralk believed Glint was a betrayer or not when he went to sleep is still rather unknown). Given this, unless Primordus was going to wake up with a 100 year gap between other ED, logic dictates that two Elder Dragons woke up at once – since it wasn’t the DSD or the other three known, it was likely Mordremoth (or alternatively, per my original speculation, a seventh ED unknown to the jotun that Kuunavang is the (former?) champion of).
