So before taking the Hunting Magic quest I have already talked to the citizens about places of power and only later I took the quest. Now the quest tells me to go and talk to those people about the things I've already talked about. The markers are set on them, but they don't have those dialogue options anymore so I can't progress the quest forward.

what do

Nevermind, accidentally stumbled on the quest item while exploring and it forwarded the quest to the correct place.

Coolio.
