Born during the Bronze Age, Kronos was credited as the founder of the Horsemen, which included fellow Immortals Methos, Silas and Caspian, who formed a group of mounted raiders who pillaged and murdered across two continents during the Bronze Age. From their exploits grew the legend of the Four Horsemen of the Apocalypse. He imposed two rules on the Horsemen: all the spoils of war were to be shared equally among them, and "We never raise a blade against each other." This, however, did not prevent tension between the members: Caspian held Silas in contempt, Methos cordially hated Caspian, and Kronos kept himself aloof, demanding ruthlessness and brotherhood from the others, a dichotomy that was bound to implode sooner or later.

No one understood terror tactics better than Kronos. Four masked phantasms suddenly materializing on horseback was an event calculated to strike panic and paralyzing fear in the hearts of their unfortunate victims. The fantastic appearance of the "Four Horsemen" could hardly have been an accident. Rather, each element of their frightening personas was deliberately calculated to maximize shock and heighten terror. The choice and design of their weaponry was an obvious extension of that premise.

Kronos' modern sword was all edges, sharp points and misery -- a portrait in terror. Each exaggeration in his design was an elaboration on history's most effective swords. In essence, Kronos tarted up a two-handed, straight-bladed broadsword.
