In the first dungeon, Heero found a familiar feeling that similar to Dramonia. From the terrain, the beast, and lastly the pure Ki. His first thought that came into his mind was that he returned to Dramonia as he entered the first dungeon.
But the first dungeon was only an isolated island in dimensional space. It was not Dramonia. Just as he thought he was in a different world, not Dramonia he met his best friend's descendant which was absurd to him.
But he witnessed himself that the technique that was being perfected with his help used against him. Moreover, for the first time, he encountered a book written in Dramonia Language. He began doubting that Earth was Dramonia and Dramonia was Earth.
And now, his doubt grew that the second dungeon appeared. The second dungeon was a Specter Territory. Based on what his first disciple told him, the second dungeon was a Specter Territory with Abyss Tree.
