I think Luke will go into hiding in plain view, so to speak, becoming the spiritual and political head of what becomes a major urban area of unimaginable ecological balance. There he will reign benevolently, but his powers will be thought so great that he's considered to be terrifying as well. Visitors from all over will seek him out, asking for that which they feel is lacking in their lives and he will point out to them that that which they seek is already inside them. Sort of.
And there'll be flying monkeys, too.
Got it. Luke is The Pin. Confirmed.
