Sandy Nichols is the local dock supervisor for the Lakefront merchant company, which owns eight commercial fishing vessels operating out of Marsilion harbor. She supervises and assists in the local loading and unloading of fish and crab vessels, makes the occasional underwater inspection of boat keels (a volunteer duty), and teaches people to swim for a modest fee in her off time. Having learned to swim at the age of three and now possessing various magical genemods which include webbed hands and feet, seal-like insulating fur, and a ruthlessly efficient respiratory system, she is quite the swimmer.
