Re: What exactly was the role of Emissary?
He never really got around to that "teaching people how to live decent lives (and be favored by the Prophets)" part, tho.
Sure he did. In Rapture he was randomly pulling insights from bystanders lives out of his prophet mojo and telling them what to do with their lives. Those electrical surges apparently beat any drugs we have today.
