Ash and Cilan are studying the Unova Region Map, when they discover what looks like another cave next to Chargestone Cave and when they show it to Iris, Iris tells them that cave was how you got Dragonosa City: Dragon Village's rival. She also explains how she went there undercover to spy on the Pokemon Laboratory and she saw them experimenting on a Charizard. Once she got back she told the Pokemon Center in Castelia City and they got the scientists arrested and the population decreased rapidly and all that was left was the metal outlines of the houses. Ash, desperately wanted to go however, Iris told them that you had to get through the Tokoro Cavern; the most haunted place in Unova. A little less willing, Ash still wanted to go. Soon afterwards Iris took them to Tokoro Cavern and led them inside to the first temple- the temple of Haxorus then the temple of Dragonite and finally the temple of Charizard.
Once they get into the sight of the ruins, Ash and Iris wander around the place and they find a map on the floor of an area called Ugarana and where it is from Dragonosa City. It shows that Ugarana is across the Dragonosa Creek but there is no way to get there as the bridge was destroyed in a fire over 500 years ago. So they have to go around the creek through Buffalon Territory- a dangerous task.Once they get to Ugarana they are greeted by the kind citizens of Liomona City, home of the New Pokecom Centre- a great place for pokemon to battle other pokemon freely.
