Or rather one incident about its past. It involved pirates.
He's going to have to come up with others. About other locations. A princess hiding in one of the places they hide, the lighthouse having something to do with the safe voyage of some important figure, or the like. Because otherwise the incident just sits there, unconvincingly: a lump, not local color.
On the other hand, it does give him a chance to show off who he is.
I think another character will get angry about some of injustice in the story.
