Legion Hype: The Tomb of Sargeras (Audio Drama)

Now this is how you make efficient use of existence assets to promote your new release and bring the hype levels up, something Blizzard is actually good at doing, and with a significant in-house production capacity for stuff like this they could easily throw this together with a few phone calls and proper scheduling. If any of this is brought up in-game when Legion goes live, even better.
