Who Is the dark voice in Starcraft 2?

Answer 1

The Dark Voice is a powerful void entity that can be seen in the Prophecy Missions. Taking a close look at the portrait you can make out that the Dark Voice has a Protoss body, and wears the Templar armor. In many opinions the Dark Voice was once a Protoss, sinse the Dark Voice controlled the Overmind and gave it an order to assimilate the Protoss. The only way it would know about the Protoss would be if he was once one of them. As we go back in time to the beginning of the Dark Templar there was Adun who taught them how to use the powers of the void. When the Dark Templar were banished from Auir a Conclave fanatic attacked the Dark Templar. In an effort to save them Adun combined templar energies and void energies to protect the Dark Templar. In the chaos of this event Adun disappeared and his body could not be found nor could he be sensed within the Khala. ( The Protoss Religion ) A theory is that the Dark Voice could very well be Adun.
