EDIT: several commenters have taken issue with the lack of a spoiler warning on this post when it went live at 9:00 pm EST. I genuinely apologize; it should have occurred to me to write one, and it's entirely my fault that one wasn't present. So consider this fair -- if belated -- warning that there's a significant, if general, spoiler in this AABT concerning an important quest chain in Wrath, and if you're trying to avoid spoilers completely, please do NOT read AABT. This column is nothing but a pile of spoilers compressed into a spoiled package and tied with a spoilery bow.
I know that in Wotlk, the players are fighting Malygos. But in TBC, Kalec/Tyri are blue dragons that help us, and Kalec is especially vital in his help to kill Kiljaeden. What's their role in Wrath?
I wish I knew. I never found any mention of Kalecgos while leveling, and Tyrygosa only got a brief mention at last year's BlizzCon. Tyrygosa's role in BC wasn't that extensive, but Kalecgos was all that and a box of crackers in Sunwell, so this is a little...mystifying. They both seem on passable (Tyrygosa) to good (Kalecgos) relations with the mortal races, so the involvement of their entire flight in Malygos' war would -- I hope -- concern them somewhat. I really hope Blizzard goes somewhere with this, but as of now I don't think you can expect to find anything in Northrend.
