Mesiterra: Age of Heroes
Mia is a small white fishing boat approximately 20 feet in length that was built and used by Oka and Solen on Elysia. Solen eventually uses the boat to flee Elysia to Zelos, and is currently using it to travel the great seas of Mesiterra.
The boat shares it’s name with the protagonist Water Cleric Mia from the game Golden Sun.
Inside the boat is a green cap, a wooden wand, and a small ship model. Each of these items used to belong to Solen’s father Oka, which seems to indicate a strong similarity between Oka and the Hero Of Time although this cannot be confirmed due to Oka’s disappearance during the invasion of Elysia.
