[@Blackbeard] did a pretty good job at explaining it, [@Jack Travidi]. Though I do see where your confusion lies.

'The Last Hero' isn't any specific character, it literally means the last legendary individual of a certain heroic period of time; let me revise my original message:

Ansus is so far divided into 2 major eras: the legendary era and the modern era. The legendary era lasted from 60,000 years ago (when Ansus was founded) and ended 1,000 years prior to the present when Ansus became unified. All our heroes come from this era. Ansus was wracked with constant battle during this time.

The modern era is the time between Ansus' unification (1,000 years ago) to the present. 

The Starless has been systematically hunting Gods for at least 500 years, extinguishing one every few decades. 

The Great Fire (the big, main fire -amongst many smaller ones- that represents the head of the pantheon) in the last few months has begun to dwindle. The last living God (The head of the pantheon) is killed pretty much as the RP begins.  

The last God brought the heroes back as a dying act.
