Does anyone know how to get out of the expansion pack Celtic and go back to Matras?
Like is there an area on that map to sail me back to Matras because I just wanted to see what it was, and I want to finish all the quest on Matras before going to other ones?
Please if you know help?

The 2nd floor of castle of logria (?) in the starting village has someone who will send you back.
