I have a quest in my queue to talk to Felicia Worthington in Regent's Square, and the helper is leading me to the Spiral door but Marleybone isn't in the list--I only have Wizard City, Krok, and Griz.
I didn't think it would give me a quest there before I had access to it, but maybe I'm wrong and need to finish something else. Am I missing something or is this an error?
There are many times a non-mainline quest (side quest, such as crafting) will assign you to a task you are not yet able to reach as you have not progressed as far on the mainline quests. Just relax and wait, or hitch a ride with a friend.
