Allow me to offer another point to this conversation: When The Nightbringer was awakened by Uriel Ventris and his pals, the C'tan fled rather than risk being buried in the rubble of his former tomb while in it's weakened and vulnerable state.

That being said, if The Void Dragon was awakened/freed, it too would likely be apt to flee from any threat to it's newfound freedom -at least until it was able to regain it's strength. So I'm not certain that the release of the Dragon beneath Mars would be as immediately devastating to the Imperium as one might assume.

The Imperium is a mighty big place, with a hell of a lot of military might... Star God or not, total C'tan victory isn't a forgone conclusion.
