StarCraft II has a deep and intricate lore surrounding it, which is hardly surprising for a Blizzard property. They are one of the kings of fictional worlds in gaming, and their work with StarCraft in particular has been delighting fans for nearly two decades.
This new trailer for the final expansion, Legacy of the Void, is almost certainly for those people. I can't imagine too many new fans being enticed by this low-fi scene, that is essentially two characters talking about in game history, but it most certainly resonate with those who have been following this story.
The reclamation of Aiur awaits. Take a look.
