Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

As the above poster said, all of that data is stored locally. Check the Final Fantasy XIV folder in your 'My Documents' folder (My Documents > My Games > Final Fantasy XIV). Has this folder been deleted or moved? Being disconnected won't necessarily affect these files unless somehow they were corrupted.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
