In an effort to efficiently disseminate as much information as possible, many of these questions are amalgamations of several slight variations asked by the US, EU, Korean, and Chinese player bases. In addition, a few unanswered questions from "Ask CDev #1" are included as well. Enjoy!
Q: Are the Warcraft and World of Warcraft RPG books considered canon?
A: No. The RPG books were created to provide an engaging table-top role-playing experience, which sometimes required diverging from the established video game canon. Blizzard helped generate a great deal of the content within the RPG books, so there will be times when ideas from the RPG will make their way into the game and official lore, but you are much better off considering the RPG books non-canonical unless otherwise stated.
Q: Where is X? (X = Calia Menethil, Turalyon, Alleria Windrunner, Med'an, Gallywix, etc.)
A: There are several "missing" characters in the Warcraft universe, but they are not forgotten! While we'd love to talk about these characters, doing so would spoil a number of the plots we have for Cataclysm and beyond. Believe us when we say that you will definitely hear about these characters when we're ready to talk about them!
Q: Why isn't there a(n) X Archaeology branch? (X = Tauren, Aqir, Faceless One, Furbolg, Murloc, etc.)
A: This is more of a game design question than a CDev one, but it was asked enough that we wanted to at least point out the following: just because a race doesn't have an Archaeology branch now doesn't mean there aren't artifacts for that race, nor does it mean that the race isn't a candidate for possible future additions to the profession.
Q: Have we seen a true titan yet in World of Warcraft?
A: No, only their creations.
Q: Are night elves related to trolls in some way?
A: See issue #5 of the World of Warcraft Official Magazine!
Q: What is the relationship between the Ancients of the Emerald Dream and the loa?
A: Troll druids visiting the Moonglade have been overheard calling the wisps who reside there loa, just as they refer to Goldrinn, Aviana, and the other returned Ancients as loa. Night elves and tauren have tried to counsel these trolls on "correct" druidic nomenclature, but the trolls thus far have been stuck in their ways.
Q: If trolls are able to regenerate their limbs, why didn't Zul'jin's arm grow back?
A: For the most part, it is the speed at which trolls regenerate that makes them formidable foes. When in balance with the loa of their tribe, they are also able to regrow digits (fingers and toes). Tales abound in troll culture, however, of those blessed by the loa with extraordinary regenerative abilities, such as the ability to regrow limbs and even vital organs lost in battle. The tale of Vula'jin the Void speaks of how he regrew almost his entire body after standing in a pool of shadowflame. But just as the loa can bless, they can also curse; troll children are taught legends of those cursed by the loa, unable to heal even flesh wounds, to instill the proper respect for their patron spirits.
Q: What races were on Azeroth before the coming of the titans?
A: Besides the elementals, the only known sentient races on Azeroth when the titans' forces arrived to subdue the Old Gods were the trolls, the race known as "faceless ones," and the aqir. Due to the Old Gods' war against the titans, as well as the extensive terraforming that followed the war's conclusion, records of what races existed before even the Old Gods' arrival have likely been lost forever.
Q: What contact, if any, have the tol'vir in Uldum had with the rest of Azeroth over the course of their existence?
A: Although the systems keeping Uldum hidden from the rest of the world worked flawlessly from the ordering of Azeroth up until the Cataclysm, the tol'vir inside did have some knowledge of what was going on outside their home: many of the titans' security devices in Uldum were in communication with the other titanic cities (Ulduar, Uldaman, etc.). The Halls of Origination were actually the system that Algalon the Observer intended to activate upon his arrival in Ulduar… which the players prevented from automatically triggering when they sent the "Reply-Code Alpha" signal from Dalaran.
Q: Why do blood elves still have green eyes?
A: Corruption from fel energies takes a long time to wear off. It's why most orcs are still green even though Mannoroth is dead.
Q: How did Sinestra survive the events of Night of the Dragon?
A: For all intents and purposes, she didn't; when players encounter Sinestra in the Bastion of Twilight raid, she is a husk of her former self, pieced together and reanimated by the powers of Deathwing's Old God master.
Q: What are the origins of stone and storm drakes?
A: Brann Bronzebeard recently uncovered evidence, corroborated by reports from adventurers in Deepholm, that proto-dragons and dragons may have origins in these—and other—elemental drakes. The inhabitants of Deepholm, the Skywall, the Firelands, and the Abyssal Maw are less than talkative on these matters, however, and most of them were not around when the elemental prisons were created.
Q: Were there ever different elemental lords before the current four?
A: Ragnaros, Al'Akir, Therazane, and Neptulon are the only elemental rulers Azeroth has had in its existence. What this will mean for the elements of fire and air with the deaths of their elemental lords is unknown, but it most certainly is not good.
Q: Why do Kvaldir disintegrate into seaweed when they die?
A: The Kvaldir typically reside deep in the ocean, where their corporeal forms would be crushed if their mistweaving magics didn't hold off the ravages of the depths. Although they remain flesh and blood in life, their deaths result in a backlash of mistweaving energies, dissolving the Kvaldir into mist over time. All that remains are patches of sea growth that had accumulated on their bodies and, of course, any loot they were carrying.
Q: Why are gnomes suddenly interested in the Light?
A: The gnomes have had an interest in the Light since they joined the Alliance, but they were so focused on technology and, later, the retaking of Gnomeregan that studying the Light didn't feel necessary to them; the dwarven priests and paladins of Ironforge served as the only connection to the Light they needed. Now that the gnomes have reclaimed a foothold in Gnomeregan and begun rebuilding their culture outside of Ironforge, however, they've recognized the importance of having followers of the Light in their own ranks. In addition, researching new methods of purifying irradiated gnomes has led to radical advances in Light-based technology!
Q: Does the Wildhammer area that was called Northeron appear in WoW?
A: Prior to the Cataclysm, the northernmost part of the Twilight Highlands was called Northeron. The rapid melting of its famed icy cliffs due to the catastrophic climate shift from the Cataclysm, the incursion of Twilight's Hammer forces, and the appearance of the creature known as Iso'rath all served to put an end to Northeron and many of the independent dwarves who lived there. Some of the wreckage is still visible along the northern coast. Fortunately, the nearby spiritual center of Kirthaven remains intact.
Q: Is Elune a naaru?
A: During a recent visit to Darnassus by Velen, he explained that the kaldorei's description of Elune, as well as the demonstrated powers of the goddess, matched his experiences with powerful naaru. He began to offer advice regarding how to commune with powerful naaru, but Tyrande thanked him for his opinion, then cordially requested that he refrain from making such outlandish claims when in Darnassus or in the presence of Elune's priesthood.
Q: The "There must always be a Lich King" mantra seemed awfully suspicious, coming from ghosts trapped in Frostmourne. Was there something else going on there?
A: To save people from generating elaborate conspiracy theories, we'll be serious for a moment and say, definitively, no. The ghosts of Uther and Terenas understood that the Scourge would run rampant without someone to keep them in check. Yes, that does also mean that Arthas and Ner'zhul were not unleashing the full force of the Scourge during their respective reigns: you are welcome to speculate on the reasons for that.
Q: What is the Argent Crusade's relationship with the Forsaken, in light of Sylvanas's recent actions?
A: Although the members of the Argent Crusade still stand by the Forsaken heroes who joined them in the battle against the Scourge, Sylvanas's actions since the slaying of Arthas have deeply concerned the crusaders. They, along with certain members of the Ebon Blade, are now watching Sylvanas and the Forsaken very closely, as similarities between her and the Lich King are increasing in number by the day.
Q: The Forsaken don't have a harbor or any dry docks: how do they create their ships?
A: The Forsaken navy is composed of ships dredged up from the bottom of the ocean. Most of them were once among Lordaeron's fleets.
Q: When undead use or are healed by the Holy Light, does it cause them any actual damage or harm, or does it only cause them pain (in addition to the intended effects of the spell)?
A: Channeling the Light in any way, or receiving healing from the Light, only causes pain. Forsaken priests do not disintegrate or explode from channeling the Light for an extended period of time… though they may wish they would.
Q: Are there long-term effects on an undead who is in regular contact with the Holy Light in a positive way?
A: It is difficult to say, as there are no known records of undead wielding the Holy Light before the Third War. There are reports, however, that some Forsaken have slowly experienced a sharpening of their dulled senses of touch, smell, etc., as well as an increase in the flashes of positive emotions that have otherwise become so rare since their fall into undeath. Unfortunately, this may be the cause of the Forsaken priesthood's increased attempts at self-destruction; regaining these senses would force the priests to smell their own rotting flesh, taste the decay in their mouths and throats, and even feel the maggots burrowing within their bodies.
Q: Why are humans who drink the blood of worgen unable to be raised as Forsaken?
A: Not only are the Val'kyr less powerful than the Lich King when it comes to raising the undead, but the worgen curse also makes raising them into undeath far more difficult than it is for normal humans. The worgen curse has roots in both the Emerald Dream (through the wolf Ancient, Goldrinn) and the holy power of the goddess Elune. In addition, those worgen who imbibe the waters of Tal'doren—through the ritual they undergo to maintain balance between the worgen curse and their humanity—have a further resistance to the corruption of undeath.
Q: Are blood elf death knights still afflicted by their racial addiction to magic?
A: No, though their new addiction, the one all Ebon Blade death knights possess, is arguably worse: the need to inflict pain. If death knights do not regularly inflict agony upon another creature, they begin to suffer wracking pains that could drive them into a mindless, blood-seeking hysteria—a far worse fate than that of those who suffer from arcane withdrawal.
Q: What has become of the blood elf Spellbreakers?
A: While they were already few in number to begin with, the ranks of this formidable fighting force were thinned drastically when their headquarters on the Isle of Quel'Danas was overwhelmed by Kael'thas and his Burning Legion forces. The lone squad that remains now exists as a relic of a bygone era, as the Spellbreakers have refrained from training any new recruits since Kael'thas's betrayal.
Q: How have the blood elves reacted to the Highborne's return to night elf society, heralding the return of kaldorei magi?
A: Because their expulsion from night elf society after the War of the Ancients was due to their use of arcane magic, the blood elves were outraged to hear that the kaldorei had welcomed the Highborne back and were tolerating the practice of arcane magic again. After witnessing the "rookie" mistakes made by the new kaldorei magi, however, the blood elves are anxiously awaiting whatever mess the kaldorei are going to put themselves in. What's more, some sin'dorei have been able to exploit the kaldorei's inexperience in order to rout Alliance forces, as seen in the "Amberwind's Journal" quest series in Azshara.
