Faithful Quartermaster's of Iuz

A trade delegation led by Captain Xendroshas come to Saltmarsh to acquire large quantities of fish (salted and preserved for transport) in the name of Iuz, a mighty cambion and demigod who rules much of the distant north. Iuz’s realm does not produce enough food to feed all its citizens, so it relies on imports for the rest, and Saltmarsh is one of its major suppliers.
The minions of Iuz have only rarely come into direct conflict with Keoland, and its ongoing war with Keoland’s rivals makes the nation an acceptable trade partner in the eyes of the king. The emissaries from Iuz pay on time and they buy shiploads of fish at once, so no one inquires too closely into the captain’s sepulchral voice or her penchant for wearing gold jewelry etched with grim designs.
Xendros sometimes has need for adventurers. She is particularly interested in tracking down an apparatus of Kwalish. If news of one reaches her, she offers magic items to those willing to recover it for her (short of an artifact, she can supply anything if given enough time to send word to Iuz). If her offer is rebuked, agents of Iuz conjure a team of demonic assassins to take the device and spirit it back to Iuz’s realm.
