Captain Xendros

A trade delegation led by Captain Xendros has come to Saltmarsh to acquire large quantities of fish (salted and preserved for transport) in the name of an enclave of the Red Wizards, further into Tethyr - which does not produce enough food to feed all its citizens (the living ones anyway), so it relies on imports for the rest, and Saltmarsh is one of its major suppliers.
While the Red Wizards are somewhat disreputable, The emissaries 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. Captain Xendros is known to have magic items for sale, and can also broker the sale of magic items.
