The Guardians of Life
The Guardians are, at the very basic core, a group of individuals who serve as worldly protectors charged with the defense of the people and the planet. They serve an unknown, but benign power that wishes only to see peace brought to the world... even if only for a time. The Guardianships of these individuals are based on this benign power's perception of the 'fundamentals of life', hence the title Guardians of Life. These fundamentals are blood, mana, light, darkness, penance and sin.
These fundamentals are based on a perceived pattern of eternal necessities and occurences in every shape and form of life. Light and darkness are eternal and ever present. Every being has a source of life, or 'blood'. Mana is present even if it is not readily accessible or even realised as a present force. And there are always beings who seek penance or sin.
Each Guardian is gifted with a certain amount of power that is true to their Guardianship. Along with this power, each Guardian is given both immortality and a cursed form that is based on both the Guardianship and personality of each Guardian. The only one exempt from this is the Overlord, the leader of the Guardians, who is instead stripped of his or her identity and given armor suitable for their form. The Overlord receives the 'words' of the power the Guardians serve and relays these words to each Guardian as is appropriate. The weapon of choice for each and every Overlord is always a scythe.
