So what do I have to do to get the NPC to talk to me in this section? I am a member of the way of the blue covenant (only because that's the only one I've come across so far) but the dude keeps telling me I'm a transient being and he wants nothing to do with me!

Gotta get a token of fidelity. You get one for helping someone else in co-op. You can also find one in huntsman's copse, but you have to do a risky drop to get it.
