The Secret of the Lost Guardians

The fall of the King of Galar long ago had left an impact on the entire Region of Galar. Especially ever since after the fall of the King, the two Guardians of the Region disappeared as well. No one knows what happened to the two Guardians known as Zamazenta and Zacian that once protected the Region. Rumors were spread about what could have happened to the two Guardians after the tragic loss of the kind King that had once so caringly ruled the lands of Galar. Would the two Guardians ever return if they were truly needed one day in time that's yet to come? Had the Guardians abandoned them all due to just having no one left to serve? Or would the Guardians return one day if someone is found suitable enough to take proper rulership of the Region? And what if, while the tragic fall of the king is a mystery, what if the two guardians held a secret of their own; a secret that had been lost to time due to having no records of this secret that stood between the two Guardians that once protected the land?
