Underworld Timeline

Due to the Fluctlight acceleration function of the Soul Translator, the time in Underworld passes at a much different rate than in real life (the FLA rate can be set anywhere from 1,000 to 5,000 times the rate of the real world). Therefore, a different calendar, called the Human Empire Calendar (HEC), is used for events in Underworld. This calendar only starts counting the time about 30 years after Quinella created the Axiom Church though, so some events do take place before the HEC.
