After talking to the order leader I wasnt able to fast travel. I restarted the game and everything but nothing worked. Just wait in the village till the damn song is done playing, few mins after the song you should be able to fast travel again.
What helped me in this case is going down and killing the 2 patrols that had joined the fight but didnt really fight. Once I killed them Birna dropped her defense pose and jumped down. Hope this helps.
