Story description
''"Now and then, rocky fragments fall from the roof of the Neath. The decks of older ships are pocked with scars. The sound is one no land-lubber knows, and no zailor will ever forget. This one has smashed the glass of a deck-binnacle. "Ill omen!" one sailor cries. "The god in the roof! Storm is angry!"''
