Take Archmage Ansirem's Letter to Magus Bromley in Azshara.
<The Archmage takes his time to study the magic.> Hmm, I can hardly believe this, why would they... <Ansirem mumbles quietly to himself.> Hero, what we are dealing with is much more serious than I had originally thought. The magic remnants upon the ley-shards are of draconic origin. What the Dragonflights would want, or need, from dampening magic in Azshara is a great mystery, but at the least we now have a source. I have prepared this letter for Bromley. Take it to him, and let him know that the Blue Dragonflight is responsible.
So, you return. What did Ansirem say about the Ley-shards?
<Magus Bromley begins to read the letter.> Oh... Well, things have gotten a whole lot more complicated if this is the case.
