So after defeating Jyrik Gauldurson im instructed to get back to arch-mage.
There is a gate blocking the way exactly after the iron door ull open after learning the dragon word.
Try all of ways i can like commiting suicide or loading previous save to fight Jyrik again but it just won't get removed. And you can't fast travel while in duegeon.
What should i do except starting a new save? Im in xbox360 version.
