I just watched the cinematic trailer and I can see this dragon is really angry in his cavern.
Got a couple of questions regarding the lore:
Who are those workers in the movie that are putting the stuff onto his body?
Why is deathwing pissed of so much?
why his breakout did not affect northrend ( lorewise)? Bolvar just watching how deathwing destroying the world he used to fight for? Why doesnt he lead the scourge against the black and twilight dragonflight?
