New Cadsoline is a pair of islands located in the Sea of Kings, north of the Brunswick Islands and south of the Cavnos Islands. The city of Newhaven is located in New Cadsoline, and both islands are territory of the Sunfall Isles in the Holy Empire of Acolytius. After the Cadsolite Imperials were pushed out of their original home on the Cadsoline Peninsula, they settled on the islands and have lived there ever since.
The northern island of New Cadsoline is simply called the North Isle, and it is the location of Newhaven. Its southern coast holds a shallow lagoon, which the city is built around. The southern island is known as the South Strand and is mostly uninhabited aside from a few small houses.
