Glaive Empire

The Glaive Empire, alternatively called the Granz Realm, are the main antagonists of Final Fantasy Adventure / Sword of Mana and its 2016 remake Adventures of Mana.

History
After Dark Lord rose to power, the Glaive Empire began a campaign of conquest, persecuting the Mana Clan and seeking out the power of the Mana Tree to dominate the world.

The Glaive Empire kidnapped some of the people from its conquered territories and forced them to fight in gladiator duels against monsters for the Dark Lord's amusement. However, a gladiator named Sumo eventually staged a rebellion against the Dark Lord that culminated in him slaying the Dark Lord in a duel.

After the Dark Lord's demise, his right hand Julius attempted to reestablish the Vandole Empire to take power after the Glaive Empire fell.
