Of the Throne (thronos)
THRONIA was the Naid-nymph of the spring, well or fountain of the town of Abdera in Bistonia, Thrake (north of Greece). She was loved by the god Poseidon and bore him Abderos (Abderus), the eponymous founding-king of the town.
Abdera, however, was usually said to have been named by Herakles after his squire Abderos who was torn apart by the man-eating mares of Diomedes.
Perhaps a daughter of the River NESTOS
