The Tory Temple is one of the few ruins on Aurora Island that has been thoroughly excavated and set up as a historical landmark. Adults are charged admission to enter, but children can get in for free, making it a great place to hold Battle Card tournaments. The lady in charge is secretly an ancient sorceress related to the Tochikan people.
The Temple is probably a reference to Golem's Fortress from the anime series, but because its location on the map doesn't fit with the travel plan on the show, it cannot be the same place. This is one of the battle locations in My Monster Rancher, but is renamed the Tornado Temple Ruins.
