Shining Force Crossover Roleplay Planning Thread

This thread is about this idea I had pop into my head recently and need a place to put it before it disappears from my head. As the topic title suggests, it's a crossover tale featuring members of the Shining Force from Shining Force 2. The events will be occurring after Zeon's sealing back into the Demon Realm in Arc Valley, where the Ancient Tower and the Kingdom of Granseal is located. Granseal is a corruption of "Ground Seal", the seal imprisoning Zeon, King of the Devils inside the demonic realm of Arc Valley. All of the principal characters that joined in the battle against Zeon and his devil minions are available to be role-played but custom characters are welcome as well. The setting and other details aren't fully fleshed out yet but I am open to story ideas and suggestions. I will be playing the role of Bowie, the leader if the Shining Force, who wielded the Force Sword that weakened Zeon and allowed them to seal him away again.

Changes:

Plot: it seems that Zeon wasn't truly defeated and has broken the seal on his own, the Jewels of Light and Evil have been stolen once again from the shrine holding The King of the Devils inside the Demonic Dimension. It looks like Bowie and his rag tag band of heroes must find the Jewels and reseal the evil before the world is plunged into eternal darkness and despair. The journey will not be easy, but Bowie and co. are surely up to the task.
