Straight-forward adventure hook, only you don't need anyone to offer a reward (though they might) (And that might create competitors).
Pros:
The heroes get to be heroic, and use all their heroic things.
Cons:
You've done this all before.
Fate Value: Equal to the Core dice of the Captor.
Example:
"Beloved and beautiful Princess Daphne has been captured by a dragon. You will rescue her."
