Frost Gate Mission.

After you finish the main one, isnt it suppose to bring you to Gates of Kryta?

Cause I just did it but im in Beacon's Perch now?

Is it messed up again?

You have to walk to the Gates of Kryta Mission. Follow the quest about clearing the centaur groups, and you'll end up at where Ranger Olson (I think that's his name) is. Just follow the path and you'll change maps to where some NPCs give you a quest to help out Aidan. Follow this quest and you'll end up in Soundrel's Rise, which is very close to the Gates of Kryta.
