So i started playing with low lvl Lahn, which i created more than a year ago, before the questline was revamped or whatever and i cant find the quest "Looking for adventurers". I was hoping to get the Narchillan awakened weapon for her but cant exchange the beginner stones that i get from the mediah questline because i did not have completed that quest. So why is that i get the beginner stones but cand do anything with them? How does that even work? How can the questlines be changed and still not having them on a character that was created like over a year ago?

Need to finish the Calpheon main quest. Old or new, doesn't matter.
