Heroes

The candidates of the Legendary and Vassal Weapons are Heroes, they have been chosen, in some cases summoned from another world, in order to wield them and protect the world from the Waves of Calamity and the Guardian Beasts. Their main objective is to defeat the enemy of the spirits of the weapons, the one who's pulling the strings behind the fusions of the worlds and giving malice individuals the ability to steal these weapons from the original candidates.

These heroes are given numerous titles, these titles are based on the type of weapon they were chosen by and the world they were either summoned to or originate from. The heroes of the Legendary Weapons are referred to as the legendary Heroes and Holy Heroes due to the numerous religions centering around the Legendary Weapons. The heroes of the Vassal Weapons are referred to as the Vassal Weapon Holders and the Vassal Weapon Heroes, in some cases, they've been given an alternative name, such as one case the Seven Star Heroes.

Additionally, there is one more type of "hero," they are individuals who weren't candidates chosen by the Legendary or Vassal Weapons and forcibly wield them against their will, these "heroes" have not been officially given a name as of yet, so we'll refer to them as "Fake Heroes." They do not have the ability to use the extent of the weapon's power.

Summoning & Selection

The Legendary and Vassal Weapons are entities, they are the spirits of the weapons that come from another world prior to being summoned by the locals of the world via summoning rituals. These spirits decide who to wield them, either through forceful summons from another world or selected candidates among the locals or foreigners of the world.

The spirits are not always able to summon their first choice of hero. In fact, only the Shield Spirits is known for always summoning its first choice of hero. The Sword, Bow, and Spear Spirits often can't summoned their first choice hero in the first place or their hero dies quickly after summoning. If summoning fails, they have to summon a backup candidate who have serious characteristic problems.

When a candidate passes on, they will no longer have ownership of the weapon under normal circumstances. Legendary Weapons are known to return to their world prior to being summoned in wait to be summoned again with another candidate, while the Vassal Weapons will choose to stay in the world, either roaming the world or staying in a particular location in search for a new candidate.

Abilities & Restrictions

The Legendary and Vassal Weapons are said to be the most popular weapons in their world. For every kind of creature, plant, and material in the world, there is a new form for the weapon and a small increase of their power. They can, in theory, even copy the power of lesser weapons made in their image: the Legendary Shield, for instance, can copy the Meteor Shield.

However, this vast power can come at a severe disadvantage: It is impossible for a Legendary and Vassal Weapons Heroes to make use of another weapon in combat under normal circumstances. For instance, the Shield Hero cannot pair his Legendary Shield with a mundane sword. The Legendary Weapon also has additional demerit, where they cannot gain experience from defeated monsters with another Legendary Hero in the same vicinity.
