The Sherriden Royal Blades

The Sherriden Royal blades are a set of 3 blades that have been handed down through multiple generations of royal families. Originally owned by the "Sherriden" family, the 3 blades are imbued with Devil Fruits to make them incredibly powerful.

Blades
There are 3 blades that are part of the Sherriden.

"Fury, the Executioner" which is imbued with the Gravity-Gravity Fruit, and owned by Velvet.

"Limbo, The Defender" which is imbued with the Grow-Grow Fruit, and owned by Lailah.

"Mercy, the Justifier" which is imbued with the Chain-Chain Fruit, and owned by Atoli.

Fury is supposed to be the offensive powerhouse of the bunch, having incredible offensive capabilities with the Gravity Fruit. Limbo is supposed to be the middle of both, being able to have strong offensive powers (Even though not as offensive as Fury), and have strong defensive powers (Not as strong as Mercy). Mercy is the opposite of Fury, having minimal offensive capabilities, but being the best defensive capabilities of all the blades.
