Please help, how do I leave the freedom isles?

[LupineDream]

I played actively for a while, then something happened and I couldn't. Now, four months later, I've resolved the problem..
.. but I've got a new one.

I've forgotten how to travel - I'm stuck in "The Freedom Isles", have completed virtually everything there is to do there and just can't find my way away. Laugh at me if you wish - but please, while laughing, describe for me how to travel away from the isles.

I've looked in every castle I could see on the map, every building I could find which wasn't marked.. Q.Q.. HELP!?!
