Bay of Mante
The second mention occurs in The Last Hero. The Maria Pesto was blown over the Rim by a terrible storm here, however it ended up orbiting the Disc until crashing on a reef in TinLing. This incident is mentioned as the only precedent for Leonard of Quirm's design of the Kite. Presumably, this shipwreck is the same as the one mentioned in Mort, but that does depend on whether Death ever did find the place.
