So now that MMO has mined some information regarding the new caster legendary, I'm really more curious by the quests and lore possibilities than the legendary itself. It seems like Anachronos is going to show us "our future," and that a recent point in the past (surrounding the Nexus) has been obscured from his sight.

My thinking is that it's probably Maly's death that was obscured, since weren't those two supposedly good friends? And if that IS the event, then the obscurer... might have been Alexstrasza. Could we be witnessing the event that brings about Anachronos' madness? Something has to happen for us to need to kill him and thus wipe out all dragon aspects on Azeroth, right?
(The last sentence was sarcastic, mostly.)

First, Anachronos is not the Aspect of Time (yet), but Nozdormu
Second, while reading the quest texts on MMO, I first thought the "event" was the Shattering, but was surprised when he mentioned the Nexus - however, I doubt the event was simply Malygos' death though, of that, he surely must've heard earlier than that, either through the other dragons or even us mortals.
I rather think this has to do with Deathwing/the Old Gods, e.g. trying to influence the succession, infiltrating and corrupting the blues. That, or the blues themselves placed the shroud, to hide something to which the other dragonflights might've objected. Doesn't necessarily lead to them becoming an enemy, though.

At any rate, the involvement of the blue dragonflight, the keepers of magic, ties in well with a "caster" legendary.

I'm more worried that we'll suddenly find out Arthas wandered into the EoE after we killed Malygos and there's another undead Dragon running about. Because there's never enough dragon bosses, much less undead ones. And back editing some more activity for the now-dead Arthas is just what the players would love to see. Everyone loves a casual and unnecessary retcon.

I happen to like dragons and the concept of dragons, but I'm burnt out on their ubiquity as dungeon and raid bosses. Been there, done that. More patches have contained dragons than otherwise - by a landslide. In Wrath every single tier had a dragon (most had multiple) - ToC almost got away without one, but they re-released Ony to make up for the lack.

Warcraft has such a rich textural history and the Dragonflights barely impacted the RTS games. Now they seem the backbone of many plot threads, if not the sole counterpoint to the overarching Old Gods thematic element. If they're a shrinking group with waning power compared to the lesser races, why does so much revolve around them? It feels like lazy storytelling - they're just easy places to hang a plot hook, both benevolent and malevolent.

I always thought humanity produced an astonishing number of evil individuals, but dragons take the cake. Humanity may have a ratio of one truly evil person in a thousand or lower (with plenty of not evil, but stupid/lazy enough to go with the flow), but with dragons the ratio of evil looks closer to 50%. For every pleasant dragon we meet, there's another wicked evil Black/Infinite dragon, or insane/twisted/tormented (poor Keristrasza) dragon from another flight.

I'm hard pressed to tie together Bronze flight, Coldarra/Blue Flight, and collecting items from the Firelands. Shadowmourne collection quests made sense in collecting Saronite (used to arm and armour Arthat's elite troops) and shards of the Throne. Collecting items from Ragnaros or the Firelands in general has no link of which I am aware to any of the dragonflights, beyond possible "It takes magic to get there and magic is bad" handwaving.

Best case the obscurity is covering something like the ascension of the new Blue Flight Leader. Someone decisive who would actually rally the remaining blues and ally with the other flights for a final confrontation against Deathwing. In short, something that furthers the plot of Cata as a whole, not a red herring or groan inducer.

Wasn't the new leader of the Blue Flight / Aspect of Magic revealed to be Kalecgos at BlizzCon?

Assuming that's still the case (Metzen has been overruled before) then why would there be any reason to conceal his ascension into that role?

Why would the Blues want to hide an event from the Bronzes if that event would unquestionably be positive for all the non-Black Flights?

One has to consider who would have the ability to hide something in time from Anachronos. He specified that it was powerful magic. Magic == Blues, which can lead to a possible conclusion where Someone is doing Something with Malygos' still-bleeding corpse. The Heart of Magic, which is apparently linked to Malygos' status as Aspect, was taken by Alexstrasza, so it should no longer be there.

"Powerful magic" could also mean Deathwing, since he's been overcharged by the Old Gods and is substantially more burly than ever before. Maybe he's retrieving the Arcanomicon from the Eye? Having a map of all the Ley Lines of the world would be useful, given that Malygos was close to blowing up the world by screwing with them, and since blowing up the world is what DW and the Old Gods are all about, it might be something worth kidnapping.

The other really strong possibility is Nozdormu himself, when it comes to someone who could obscure an event in time from the Guardians of Time. I actually think this is the strongest possibility, since it'll tie in with the CoT:WotA raid, AND tie the Infinite Dragonflight story in with Cataclysm. Hopefully we won't actually end up killing Nozdormu, because like you Exemplar, I'm sick of killing the gods because they go crazy.

To go back to your earlier comment of dragons being overly-common boss encounters... everyone with an interest in fantasy has a basic understanding that Dragons Are Powerful, and overcoming the powerful is a huge psychological reward. If you want to introduce a different monster of some kind, you have to spend time leveraging how powerful they are, because it can't be assumed at face value.

Burning Crusade was able to do this with a minimum of dragon bosses (CoT: Black Morass, CoT: Hillsbrad, Felmyst, Netherspite, Nightbane... that's it, right?) because the Legion was pre-established as powerful in WC3, and a lot of time was spent building them up in quests and world encounters. Perhaps the over-use of dragons in Wrath was compensating for a dearth of dragon-fights in BC?

The moment I saw "Nexus" I thought it was a tongue-in-cheek about the way the Nexus War plot line from Wrath was handled poorly. It was a major lore thing all the way while leveling, and was the entire reason Dalaran was floating over Crystalsong. Yet we killed Malygos, Aspect of Magic, in the first tier or raiding to minimal applause and absolutely no follow up to something that would have a huge impact on the lore. So now we get Anachronos going "lol I don't even know what happened."

Anyway, I think Firelands is only relevant because getting powerful fire elemental hearts to reforge the Eye of Time seems appropriate. Not because there's any connection between Firelands and the Bronze Flight, but because you've got to use something to reforge powerful artifacts and Firelands holds a rather convenient source.

That's the problem with a two-faction game which has symmetrical content. A member of the playable races has to sail far over the Moral Event Horizon before he can be used as a raid boss, because both sides have to think it's right to kill him. So most bosses wind up being under some form of absolute control, or from races that are either neutral or definitively antipathetic.

I think that the two things are inextricably linked though, the old gods began the decline of the flights over 10,000 years ago with the fall of Neltharion and the creation of the Demon Soul. We as mortals are now witnessing the effect that this gambit by the old gods has had there is already 1 aspect down and we will be killing another one in just over a year's time. The aspects were one of the security measures left by the titans to protect Azeroth from the Old Gods and now members of the black flight are working for the old gods, greens have an old god to contend with behind the emerald nightmare, the bronzes have been heavily involved in the AQ arc, the blues have been decimated (they may be regrouping but their flight was already tiny in number before the nexus war, and Alexstrasza's heir has now been killed by Sinestra. I think this is all leading up to the point where Dragons can eventually no longer play a leading role in events on Azeroth, and it is a recurring theme in fantasy that the older races eventually go into decline and younger mortal races take up the mantle of defenders of the world. So i guess before we can reach the point where Dragons are no longer front and centre, we need to finish the realisation of their decline.

MMO-Champ mentionsan event called "Tarecgosa Intro". Trying not to read too much into it, but I think the rule "If it has an intro, it's an enemy" is fairly true. Well, apart from Thrall, but he runs Blizzard.

So we have an intro for a blue dragoness, a mention of "powerful magic" (the Blues' domain, as someone above pointed out) and something happening in the Nexus...I'd say them icy lizards are up to something - they might just have good intentions.

By the way, how would Kalecgos' ascension to Aspect of Magic work? Is he supposed to receive Malygos' power?

"Intro" could just refer to some NPC appearing. Let's not overspeculate from scarce datamined stuff.

It's under the "phase" cathegory, alongside things such as "Forlorn Spire Assault", "ZG event" and "Hyjal Regrowth Invasion". So it's not "Intro" as in a boss making a speech as you enter his room.

My thesis was half-humorous, but the blues do have a history...

I'm smelling another rescue encounter.
