Sicily is the largest island in the Mediterranean Sea. It is an autonomous region of Southern Italy, along with surrounding minor islands.
In 2018, Arthur Curry and Mera were in Sicily to look for Atlan's Trident, after finding a map in the Kingdom of the Deserters that lead them there. Little did they know that Orm had found their location using Mera's bracelet, and sent Black Manta and the Men of War there to track down and kill them. They were unsuccessful, and Manta fell off the cliff to his apparent death. Arthur suffered an injury from the battle, but was healed by Mera.
