Vassal Weapons

The Vassal Weapons (眷属器) are entities, they are spirits of the vassal weapons that come from another world prior to being summoned. They decide the candidate to be forcefully summoned to another world to wield, however, different to the legendary weapons, these weapons has the ability to be summoned without a candidate present, giving the ability for the locals of the world to wield them if they prove themselves worthy. The users who wield these weapons are given the title of Vassal Weapons Holders or Vassal Heroes.

The locals of her world are unaware of the present of the eighth vassal weapon.

Origins
The origins of the vassal weapons are shrouded in mystery, they have a deep tie with the Legendary Weapons and their respective worlds.

The role of the vassal weapon was initially believed to be used to invade worlds which are fusing with their own, to eliminate the legendary heroes. Successfully eliminating all the legendary heroes should save their own home but at the cost of destroying another world. The role of the vassal weapons are now believed to assist the legendary weapons and transport to other worlds to strengthen their own weapon.

Summoning & Selection
The vassal weapons were summoned through rituals, prior to being summoned they can be summoned with or without a candidate being present. When a wielder is deceased, the weapon chooses to roam the world or remain in a certain location in search of a new candidate that proves their potential.
