Careoc was once a fiefdom of House Chantris. It became part of Amber when an unknown prince walked its broken Pattern, making it whole and adding the shadow to Amber itself. It is now the northernmost part of Amber.

The inhabitants of Careoc are traders and fishermen, and the bulk of them live in a small coastal town protected by a horseshoe-shaped bay. The Baron of the town is currently in talks with House Bayle about how best to integrate the people of Careoc with the larger population of Amber. For the moment, an agreement has been reached whereby House Chantris can continue to use Careoc as a military port, and House Bayle will begin clearing the unused land around the town for agriculture.
