private;

I'm sorry to hear. And I know very little about alchemy but that much makes sense to me. If I can offer a suggestion, you could ask a few select people for help. There are a lot of experienced magic users on board so maybe one of them would be able to help strengthen whatever link keeps Al's body connected to that armor, or at least build some kind of shield to keep it from being damaged, weakened or destroyed.

I know you probably don't want to go around telling complete strangers about this, but maybe you can get to know some of these people first, and trust them enough to bring this up eventually.
