Houses of Hermes Mystery Cults Question

Can anyone help? I don't have my books to hand and need to locate whether Ophia Isle-Warden's sept mentioned under I think Clan Maruhs in the Bjornaer Chapter of HOH:MC is located in the Aegean or the Ionian Sea? Sorry to be a pain!

Aegaen sea, HoH: MC, p. 14

According to the book, she's of clan Sirnas and the isle's in the Aegean.
