from Mar Sara, and Sarah Kerrigan, a psychic assassin and Mengsk's second-in-command. The second episode of the game sees the player as a cerebrate, a commander within the Zerg Swarm. The player is ruled over by the Zerg Overmind – the manifestation of the collective consciousness of the Swarm and the game's primary antagonist – and is given advice from other cerebrates of higher rank and status while accomplishing the objectives of the Swarm.
