How to access Masteries?
If you have HoT, all you need to do to unlock masteries is reach level 80.
Wait, I’m sorry, you also have to complete the Story: Torn From the Sky. But you don’t have to finish the previous seasons to do it.

Do the first chapter of the 2nd part of living story, don’t even need to have done any of the previous season. Active it in your story journal.
Just make sure you go to your Story Journal tab and select the heart of thorns story to start it. You can ignore season 2 if you wish or do it later. It adds to story continuity but is not required for HoT or masteries
