Karst is a male human who runs the ferry from the Phlan docks to Thorn Island.

He is a bitter, elderly fellow who has worked as a ferryman for nearly 40 years. Recent events in Phlan have taken their toll on his livelihood and he has not seen much in the way of coin. Were it not for his old age, he would have left long ago. He will ferry people to Thorn Island for a fee of 1 gp, providing they have at least a flimsy excuse for going there. (The island in theory is not supposed to receive unexpected visitors.)
