Port Llast (formerly Grath's Hold) stood on the High Road some thirty-five miles north of Neverwinter. It was a small town of 700 folk mainly known for its skilled stonecutters and excellent harbor – a small bay sheltered by a high, rocky spit, with a fine beach and inlet. The port was overlooked by cliffs on which boulder-hurling siege engines were placed. Port Llast was ruled by a First Captain, and was closely allied to Neverwinter (largely for protection from Luskan, who desired a more southerly harbor for its warships).
The harbor was home to a twelve-boat fishing fleet, but two of the ships were in very poor repair. Port Llast's prime land-bound mercantile enterprises were quarries on the coastal headlands just south of the village. Other than harborage or stonecutting, there was little else to recommend it to the traveler, for it was a tense, suspicious place, always expecting treachery or attack from Luskan. In 1356 DR the town was ruled by First Captain Haeromos Dothwintyl, a retired stonemason.
