Centuries ago, the first generation of the Givean defeated the Darck Order and sealed them away. Many years later, the newest generation of the Givean must pick up where their predecessor left off.

Cool idea, and I think adding more information would make it even better! Maybe shortening the first part like “Centuries after [this person / these people] sealed away the Darck Order [In this specific way], [the important characters] of the Givean must continue. And adding the new way in which the Darck order puts up a fight!
