I'm on Terra, but I Built a Frankenstein Parallel World

The dragon Youlong, who transmigrated to the land of Terra, has been having a rough time lately, because it went and did something huge. As a spacetime cloud dragon with a bit of a connection to Number Dragon, and which had closely studied Dialga and Palkia's creation of the world, it ended up creating a new world of its own after transmigrating to Terra. At first, things were still under control, but everything seemed to change once this new world became a parallel world of Terra and a passage linked the two together.<br><br>Kal'tsit: You call that place over there, teeming with all kinds of strange creatures, Terra?!<br>Doctor: How come the me in the other world seems to have already married someone called Priestess? Huh? Kal'tsit, why are you staring at me like that?<br>Ch'en: Explain to me what the Swordsoul Sect is! What is a Deepsea Dragon? Why has Yan changed into something I don't recognize?!<br>Ulpianus: So you're saying that the parallel world's Ægir wanted to turn the whole world into an ocean, picked a fight with something called Kyogre, and ended up beaten into a plush ball? No! Terra isn't like this where we're from!<br>Youlong: I think so too, but this world keeps coming up with all these elements on its own. What am I supposed to do about it?! (Aaaah, how am I supposed to write the synopsis? Can someone teach me?!!!)
