Blizzard has released a series of videos detailing the events that occur throughout the Fangs of the Father quest chain. Even better, the entire recap is narrated by Wrathion himself, describing the events of the quest chain from his perspective. The entire thing is capped off with an insinuation that we just might run into Deathwing's heir beyond the mists of the sea.
You can watch the first part embedded above and the following three parts either on Battle.net or behind the cut below. In addition to the videos, Battle.net offers a list of the first 100 people to complete their Fangs in each world region.
