I can't believe this is Dein Nomos...
the proof of imperial succession.

Yuri, you can become the emperor!

This is just for decoration.
I wouldn't wanna be the
emperor even if I could.

Shouldn't you have more
aspirations as a young man?

That's coming from you?

The lost proof of imperial succession...

The strife surrounding the throne
could be traced back to when
that sword went missing.

Could Duke have stolen it?

Hey, if you're trying to tell me
you want to collect it on behalf
of the Knights, spare me.

I know.
Now's not the time.

Duke went around using that
sword to control aer krene...

Oh! So Duke's doing
the same thing as
the Entelexeia?

Maybe so.

That sword...it produced the same
phenomenon as Estelle did.

Maybe the Rizomata Formula was already
worked out once before? But then, why
was that information lost?

Maybe it's related to the cataclysm, like
the way that the blastia were lost?

Why did that become an Imperial treasure?

There are tons of things we don't know
about this sword, but let's wait to figure
them out until we've settled things here.

Right now, rescuing Estelle
is our top priority.

Right. Let's hurry!
