The Rippled Sea is one of many Twilight Seas within the Shimmering Seas universe.
100 years ago, a cataclysmic event known as "the Collision" forever changed the Rippled Sea: four continental islands were smashed together inexplicably and without warning. In a split second, entire cities were destroyed, whole mountain ranges rose up, and vast regions were flooded. The loss of life happened on an unimaginable, unspeakable scale. In the chaotic years immediately thereafter, many pre-Collision cultures, histories, governments, and ways of life disappeared or were dramatically reinvented. Some however, survived.
Each of the four pre-Collision islands, though they may now be geologically just one island, are commonly referred to individually. No name exists to refer to all four of them in their entirety. They are: Himhum Island (now in the northwest), Katinka Island (now in the southwest), the Island of Skjar (now in the northeast), and the Island of Ghorlash (now in the southeast).
