Well, "Bridge of Forever" doesn't introduce you to the Doorman, but it does send you to First Ward and tell you how to get there via the Imperial Underground.
Possibly a Gold version of an EAT, like a DUST or TEST trooper would have an arc that extended into First Ward. I'm thinking that while Loyalists can take the missions from Doorman and so on, narratively, considering the War on Magic, they really should have a different introduction to the zone.
