"The Regigigas temple in Snowpoint City, my original hometown." Chuck said.  "That was where Tru got his start as a Pokémon Researcher.  Then he began exploring the different regions, learning the legends and exploring ruins, temples, and excavation sites, as well as studying under the professors of each region.  It was his goal to uncover every legend of this world and learn as much as he could about them.  He would have loved to meet you guys, and all the Pokémon you've collected, since he did research on all of them.  The last we heard of him, today 10 years ago, he was headed for a region known as Galar, to look into a possible pair of legends dealing with Pokémon seemingly based off a sword and a shield, potentially of the lupine variety.  However, it was then that we lost contact with him.  Even the International Police looked into it and couldn't find anything.  It's like he just vanished into thin air."
