Upon her return journey from Morea, Eschive was shipwrecked.[3] Since Athens was a fief of the Principality of Achaea, the decision was in the hands of Philip I of Taranto, Prince of Achaea, and his suzerain and elder brother Robert of Naples. The two referred the question to the High Court of Achaea in 1309, which met at Glarentza and declared Walter the heir on the pragmatic grounds that he was male and an active soldier, better suited to defend the Duchy. The disappointed Eschive thereupon appealed to the Virgin Mary before the altar of St Francis at Glarentza, asking that Walter and the judges die without heirs of the body if they had wrongly judged against her.[4] Eschive in fact outlived Walter, who was killed at the Battle of Halmyros in 1311, but died the following year in Nicosia and was buried there.[4]
