A seaside castle ruled by a King Orions (Orians) in the Post-Vulgate Suite du Merlin.

When Arthur set hundreds of infants adrift at sea in a vain effort to destroy his incestuous son, Mordred, the boat came ashore at Amalvi. Orions took the children into his care.

There is a town called Amalfi on the Gulf of Salerno in southern Italy.
