In consideration of our upcoming release of "Veil of Corruption Chapter II" on February, 11th here on warcraftmovies, I have made a 12 minute long summary of our first chapter.
Normally I would say "Go and watch the first part". But it was only voiced in German with English subs. So I guess it might be much easier for the international audience to get familiar with the storyline of the VoC trilogy.
I strongly recommend to watch either this summary or the first chapter of Veil of Corruption as long as you're going to watch the 2nd chapter on 11th.
If don't know what Veil of Corruption is and what is expecting you, watch the official trailer
