Perhaps like Ericthonios, just one of many Amaurotines never encountered, Sundered like the rest. Who can say? Also, what an interesting way to phrase it. 'Another from the same star'. Does Taiki mean meeting Erichthonios and then Themis... or that both were from Taiki's star?

The Amaurotine does know that 'star' isn't a common term used by other tamers to refer to their worlds and realms. But it doesn't prove anything either.

Then you've met him. And it would be nice to meet. Though would you explain what you meant by it simplifying things?
