The quartered tower is not just one tower, but four sitting at the cardinal points around the Old City of Pa'arenthia. The tower are a great distance from the city and their purpose has been undetermined, as only two of four towers have been found keepers.
A towers keeper is rumored to have been chosen before birth and when each child reaches a certain age in which they are able to harness some deal of power, they are escorted to the remaining towers.
The towers are home to Scholars, priests, alchemists, and other employed by the Government in order to study the origins and effects of the tower, to try and ascertain their purpose.
