Ocean Hill was given to Coriane Jacos as a gift from Tiberias Calore VI. It was later damaged by Maven Calore. Tiberias Calore VII had mentioned that Maven never liked Ocean Hill, since it was too small and cold. When Mare Barrow and Diana Farley were running through the palace, trying to escape the guards, Cal lead them down a secret passage in the palace. While running, Mare saw faint yellow banners, which is the color of House Jacos. It is known that the banners were once Cal's mother's.
