Nicholas was the lord of the castle of Saint-Sauveur,[1] an unidentified site, perhaps identical to the monastery of the same name, located some 15 km east of medieval Arcadia (modern Kyparissia) in Messenia.
[3] By 1302, he served as captain of the region of Skorta and warden of the Barony of Kalamata for Matilda of Hainaut, who was absent as she had been wed to Guy II de la Roche, Duke of Athens.
[5] It was in this capacity that he arrested Margaret of Villehardouin, who maintained her rival claims on the Principality against the Angevins, on her arrival at Port-de-Jonc in early summer 1314.
Ferdinand arrived with his army in late June 1315, and although a first attempt to land at Glarentza was beaten off by Nicholas and the troops of Achaea, a second succeeded, and the Achaean barons withdrew to Chlemoutsi.
His son, Stephen le Maure, succeeded him, and was also lord of the castle of Aetos and Baron of Arcadia through his marriage in 1324 to Agnes of Aulnay, heiress of the barony.
