I'd assume that with communications lost at the end of Brood War, Earth assumed DuGalle had failed and have spent years planning another invasion. And with these Xel'Naga artifacts, their now even more dangerous. Ultimatly, this would result in the Voice in the Darkness emerging as the next big bad. And goodness knows what will happen with him around, considering he's supposed to be worse than Amon.

Good ideas on the Protoss. It seems Artanis is going to face some internal problems, since we have multiple Protoss cultures as one people. But that's easier said than maintained. Artanis would definitely oppose going to war against the Terrans unless he had no other. So it'll have to be either renegade Protoss, acting outside of Aiur's interests, a false flag terrorist action that causes Artanis to reluctantly declare war on the Terrans, or Alarak and his followers.

Any ideas of your own?
