Hassan is a port town in Shining Force II.
Background
Hassan was a port town, but due to not trading, the town became desolate. You have to beat the Kraken to get to here. You will find Rohde here; If you had already gotten the Achilles Sword in Ribble, Rohde will ask what smells old. He will then follow you around for a little bit, before joining you later on.
Once you beat Taros, another weapon dealer will appear, that has upgraded weapons. Some, but not all, require you to be promoted.
In Shining Force Gaiden: Final Conflict the Shining force regroups here after their 1st encounter with Mishaela. They agree to recheck the temple and find Ruburan and bring him back. Mishaela attacks the village when they return and they fight off her forces. After beating off her men the Force confronts her as she reveals she came here as the elder is the only one there who knows of the Caravan and they capture him as they escape.
Inhabitants
Rohde - He will join the force shortly after you beat Taros in the Taros shrine.
Rick - Shortly after the battle, go to Hassan again, and you will find him there.
