d100 Mystery Island Settlements

I often like to tease adventurers with island treasure maps for a long time. Eventually, they will plan a trek to several islands which allow all kinds of hijinks. My fave is deathwatch beetles living in a rotting log cabin that proved to be one of deadliest fights i ever ran..
