It was common folklore that Aponivi Gold had a mysterious magic attuned to it. It is said that It would follow and spite those who had no right to its possession. They said it'd be a suicide journey yet desperation forced their hand. The bandit crew of a steam train escaping with a spoil of gold and treasures met their inevitable demise while crossing an uncharted chasm. This event triggered a number of legends which told of a forgotten steam train buried with its bounty.
