Shiro Tagachi

Shiro Tagachi was the bodyguard of the Emperor of Cantha who killed the very Emperor he was sworn to protect 200 years prior to the present game time. For this betrayal he was slain at the same spot by the heroes of Cantha who were present. At his death he uttered a terrible cry which has laid a curse upon the Cathan continent for 200 years. See video link below for a rendition of this event.

The tale of Shiro Tagachi in present day Cantha is more of a bogeyman story mixed with myth and a cautionary tale against the dangers of magical power.

History
200 years ago, The Emperor of Cantha was attending the Harvest Festival in Kaoya Zun Temple and as he bowed his head down to pray to the gods, Shiro came up behind him and slew him in cold blood in that holy place. The champions of Cantha who were present at the ceremony all rushed to avenge their Emperor, but Shiro was without match in the use of the blade. He slew many of the rampaging soldiers until two champions finally bested him and killed him with the very blades he used to slay the Emperor.

In his final living moments, overcome with pain, rage and and malice, Shiro let out a terrible cry that caused a Jade Wind to sweep across the lands of Cantha, petrifying the forest and turning the sea into pure jade.

Prior to his betrayal, Shiro was an honorable man entrusted with the greatest duty a soldier can take on. It is unknown what turned him into a cowardly traitor and murderer.
