'so Lationusi lived on Mu just in a previous life. By many reincarnation, he eventually arrived on Thiaoouba. This is confirmed by some later conversation and Michel's Japan interview .In the japan interview Michel said Lationusi "became slowly slowly by refinement of different reincarnations, finally ends up on Thiaoouba ".
so it is clear to me that Lationusi was a person (king) on Mu, and finally arrived on Thiaoouba.
but in the book, there is a confusing sentence, chapter 9 ,page 115, Thao said :" 'Jesus, Michel was sent to Earth from Thiaoouba almost 2000 years ago - just as Lationusi also went to Earth and has returned." so it implies that Lationusi was like Jesus Christ, sent by them to be the king of Mu and returned. That is to say ,Lationusi always lives on Thiaoouba, at least 14000 years ago and now.
so, how to explain that?
The assumed timeline would perhaps be alike; go through refinements slowly > end up on Thiaoouba > go back as the last king (etc. a special mission) > return again 'finally' to Thiaoouba.
