I posted about this on Beta, got no dev response, and it went live like this. The two mission/raid givers in GD are backwards and need to be swapped. Zrelik: located near Velk's, gives The Restless Assault mission/raid that takes place near Thurgadin. Horasug: located near Thurgadin, gives Seeking the Sorcerer mission/raid that takes place in Velk's. He even 'shows' you a secret entrance to Velk's - right from Thurgadin?
