Wolfsrose I don't object to just shoot me your ideas on how you would go about it.

I'm inclined to go for a mercenary group employed by Raynor after the fall of Korhal to hunt down renegade zerg groups (Cerebrates or Broodmothers don't matter), and when the time comes call in for protoss reinforcements to take out the leader. Though as they get further along things start getting complicated. To what extent is debatable.
