Flavius met Radium when he tried to assassinate Dionysos. Being cornered and intimidated after the botched assassination Radium had no choice but to team up with Flavius. Wealth redistribution business and decapitating people is something Radium enjoys so he has been so far a loyal companion of Flavius and his associates.

Radium says he’s from Stygia but Flavius thinks he’s more likely from the eastern desert south of Turan. Cobras are notoriously bad at geography but people like to cling to their pathetic lives and won’t try to correct Radium.

Early years taught Radium that he’s a natural born killer and his victims always died an agonizing death. People were jealous and afraid of his great kill-skills and he was forced to live in the desert. His life was tough and he preyed on rodents, lizards, toads and an occasional chicken he stole from a nearby village.

Finally, after an indefinite time, Radium felt so lonely and tired of living on his own that he decided to trek through the land to find a wealthy patron and put the natural death-dealing abilities to good use.
