Roccino Isle sits off the rocky headland approximately 200 miles northwest of Venza. The lighthouse there protects ships that sail around the headland on the way to ports north, particularly Tritower and the cities of the Ouhm Delta. The keeper of the lighthouse is young Giocco Lanterna who took over the work after tragedy struck his family.
Roccino Isle, Giocco Lanterna and the lighthouse were first featured in the adventure Little Rock of Horrors.
