Seniorious

Seniorious (セニオリス, Seniorisu) is a Carillon/Dug Weapon that's currently owned by the Orlandry Merchants Guild.

Background
Seniorious is the strongest Carillon/Dug Weapon known to have ever existed. Back when the world was still intact, Seniorious was also called "The Brown Dragon Killer," "The God Breaker," and "The Secret Blade of the White Scabbard."Due to its high standards, the Carillon is extremely picky when it comes to choosing its wielders. Seniorious not only requires its wielders to be incredibly talented, but also for them to have a tragic background of some sort. The wielder is also doomed to a cursed life where they will never find happiness, even upon death. It is also explained that Seniorious also chooses people who accept that their hope can’t come true, but still use the power to create a new one even if it's not the same one that they want.

History
It is said that Seniorious was born out of a miraculous incident on the battlefield.

Physical Composition
Seniorious is a long heavy sword that is composed of random multiple shining talismans e.g. one that prevents nightmares and one that prevents a person from burning themselves on their tea. When combined, the talismans glow blue when activated with Venenum and can unleash devastating blue blasts that can slice a Sky Island in half. However by themselves, all of Seniorious' talismans are relatively useless except for in normal settings.

Special Abilities
Seniorious' special ability is the ability to kill anything and everything. There are exceptions and it is capable of killing even immortal beings like the Visitors, by cursing their bodies into a death state. The only known "downside" of this ability is that the wielder needs to activate it with their Venenum manually.
