‘Secure Resources’ Greymane quest

Allo, I just need to know I’m not jumping ahead of myself (story-wise).

Currently at the beginning of Chapter 4. This quest asks you to do an internal defence mission for an Azerian estate.

My trouble is I’ve not been able to get close to vendors because of the unwelcome >!Inquistors!< starting fights… my question is do I worry about Demeniss e.t.c much later?
