Guardians have been called many things throughout the millenia, mainly in good connotations; guardian angels, fairy godmothers, protectors, advocates, guiding spirits. Others have tried to demonize them, calling them incubus or succubus or the minons of the devil.
Guardians are former humans, plucked from death to serve a greater purpose, to guide humans to better destinies or to fulfil wishes to those deemed worthy. The Elders oversee the Guardians, making sure the Guardians stay within the rules. But events unfolding in the first book, 'Twenty-Four Hours' will have lasting ramifications for Elders, Guardians and the mere humans trying to survive.
