The Ionian sea is an elongated bay of the Mediterranean sea. It is just south of the Adriatic Sea. Normally the sea is calm, but on stormy nights it becomes a monster. Fog that comes off the sea can block view of hidden reefs. Many fish live in these waters including the non fish octopus. Captain Alexander lost his ship in these water not without making it to land. Marco got swept out to sea during the storm and his friends followed after him. The people of the Ionian coast depend on the sea. With what boats they have they go off a fish near a crab shaped reef. Marco and his friends with some help of the local villagers made a diving bell and dived into the Ionian Sea to collect the treasure that was lost at sea.
