Clam Island is a small island off the coast of Elient in Tethyr. It is technically a part of the Kingdom but it operates completely independently with its own military and government. The island is 80% forest with only 3 large cities; Whitestrand on the west coast, Blackhollow on the east coast, and Silverpearl on the south coast.
Mage's are rare in Clam Island as most of the people who pass through or live their are sailors, nobles, military knights, or traders. As such, there are no magic shops or clerics havens on Clam Island.
Clam Island is home to many types of beasts living around the islands waters as well as in the forest. The island is 95% human so there is very little diversity and any non-humans are treated with much hostility by the general public. Each city has its own leadership and set of laws but they are united in one aspect, The Defenders of Justice. The Defenders are a militia group who's primary job has been to protect trade ships coming too and from the main land. It is the main shipping port for transfers from Eberron in which most of the imports go directly to Nar Shadda for further distribution.
Over the last decade however, the island has been plagued by a pirate gang known as The Bone Crushers lead by the dreaded "One Eyed Marco" who attacks merchant ships, looking specifically for spice but will take anything, and sells his loot to various underground markets in Nar Shadda. The gang is also known to handle Lady Me's drug running in and out of the kingdom.
