Krost was a city in Lanachrona.
During Alucius's life, it was larger than Borlan, but around half the size of Hieron. It was near the wine-making area of Vyan Hills; to the southeast of the city were rows of grape vines. Korst was a city of wine merchants and glassworks; the wine from Vyan Hills was bottled in Krost and sold across Corus. Korst also produced wine goblets. Near the city was a hill with fine sand suitable for making glass.
