The Shattered Isthmus is an archipelago that stretches across the Azure Passage. Its name comes from its appearance, as the chain of unnamed islands seem to connect the continents of Impatria and Jalafar. Specifically, they stretch from the southern tip of the Lashed Peninsula to the northern point of the Savage Lands. The Isthmus is often associated with Estlan.
The Shattered Isthmus is fully uninhabited, as the islands within the archipelago lack the resources needed to support a settlement. After the initial voyages to map this region of Asobria, few ships have bothered sailing through the surrounding waters. All that remains to be found in the Isthmus are seabirds and endless seas, though some believe there may be more to discover far beyond the archipelago across the Great Abyss.
