Fairly sure all you get from this event is another enemy camp (a graveyard, ruin, hut, etc.) on your map that may or may not have better loot, it doesn’t tell you where that camp is exactly, though. You’ll have to compare names of those camps on your map that you aren’t sure were already there before the event to find the one mentioned.
I once got the name of a camp I had already discovered… was a while a go and might have been a bug, kinda annoying.
