I think a connection to the first games is the only kind of 'reveal' that would warrant the kind of day one discussion Swen is talking about. Whatever it might be.
Maybe the artifact is a prison that the last bit of Bhaal essence our Bhaalspawn hid away, and "who do you dream of" is a pocket plane-esque specter of the Bhaalspawn.

Or it could be something something the Absolute is what! something. Ho hum
