Q:
Following up with Rox
I’m pretty sure all of the instances are account-based, not character-based. I never did any of the initial Black Citadel / Hoelbrak stages with my Elementalist, but I was still able to enter the instances in Cragstead and the Hatchery because I’d “unlocked” them with other characters and thus they were opened for my account in general.
So you should be able to follow up with Rox just fine regardless. Are you sure you’re going to the right place? The follow up for Rox is in the dungeon / stockade in Black Citadel (which is in the “basement”), not the upper floor where the first quest was.
One they blond Rox like Kormir but she still manages to join the warband of Rytlock due to learning to see with her hearing. I will desire to follow the story of Rox. Till they she is just anime kitty.
