The Seven Elemental Blades

Incendium
Incendium is the blade of fire, and was the first blade to be created and used. It can set anything it touches on fire and melt most objects instantly, though the heat of the blade can be controlled by the user. The ICM gave it to the keepers of the Phoenix Sanctum, and the blade has since been wielded by many Sanctum Guardians, most recently Tarab Pazza.

Aqualacus
Aqualacus is the blade of water

Ventaurus
Ventaurus is the blade of air

Petracilex
Petracilex is the blade of earth

Fulgelec
Fulgelec is the blade of lightning

Saber
Saber is the blade of shadows,

Imperilux
Imperilux is the blade of light, and is the most powerful of the seven blades. It can shine a beam of light so powerful that it instantly blinds those who look at it and melts most everything it touches. The ICM hid it in secret shrine where it can only be accesses if the other six blades are present.
