Shining Force II(1993)

As a student of Astral the wizard, you and your friends study all the usual subjects: reading, writing, and sword fighting. As your time at school draws to an end, dark events are taking place on the island of Grans. The two Jewels which seal the Door to Darkness have been stolen, allowing a creature of awesome power to be unleashed. Finding where the Jewels were taken, and why, is a task only the bravest of adventurers can undertake.
