I unfortunately don't think it's related to the Airs at all. Besides, Enigma is an abandoned project of Alexis Kennedy, FL's original developer, and it's extremely unlikely it'll ever be touched upon. There's nothing behind <a href="/wiki/An_Intimation" title="An Intimation">An Intimation</a> at all. It's even been confirmed that it's never been in active development.

That being said, I'm not going to stop you. Heed Neil. It's wiser than to Seek Name.
