Estregales is the eastern-most Cambrian kingdom. Estregales is a land ruled by Irish conquerors whose ancestors came over a hundred or more years ago. So many Irish tribes people came that the region is now Irish rather than Cymric. It includes the counties of Gower and Dyfed.
Carmarthen is the birthplace of the great magician Merlin, and the capital city of the kingdom. It is protected by a magical tree which will stand until the city is about to fall. The city is not walled, but the tree is.
Menevia is the site of the monastery founded by Father Dewi.
