There are all sorts of neat implications in the text. For one thing, the mortal races of Azeroth seem to be meddling with great powers more than ever before after the fall of Deathwing, and the warlocks of Azeroth are afraid of being eclipsed by other rivals (like, say, mages and their weird time magics). In addition to the mention of figures like Ritssyn, it creates the idea of a secret warlock super-cabal that dispenses fel magics to other groups of warlocks and ties in events from the death of Illidan to the recent destruction of Deathwing as teachable moments that gave various warlocks eureka moments. "So that's how you turn into a demon! I get it!"
It's definitely worth a read, so go check it out.
