Always Around When Needed

If a monster is ravaging a town, chances are a group of heroes will be nearby. Send a lone runner in a random direction to spring until they’re about to pass out from exhaustion, and just before they collapse they’ll find a group of heroes that can rush to the rescue. Or arrive in time rescue the survivors.

That is, unless you have an impressionable youth with great potential and natural talent who could one day become a great hero. In that case your a backstory and everyone is screwed.
