Rena is positively confused by the things these guys are saying, yesterday she didn't even know anything about outer space and other inhabited planets. An interesting bit: in the Rena storyline of the game, you can trigger a Private Action with Claude in which he will ask her about what she thinks is 'beyond the sky', to which you can select the answer 'maybe another world?'.
What I could gather from the information these ten men (?) are providing is that:
- they created the Quadratic Sphere (i.e. the Sorcery Globe), which automatically makes them our enemy
- they are from Nede, the same planet Rena is from, but how both have come to this planet and why is still a mystery (and for them it's not really explained even later on)
- they possess (I think) a crystallized form of energy called the Quadratic Key, which is similar to Rena's pendant, but are surprised she has one as well (this IS explained later on, but I still don't know what a Quadratic Key really is or what it's used for)
- each one has a different personality from the others, which will make it slightly more enjoyable for us when it's time to kill them all; however, given that there was a boss battle just a little while ago, and we've still got another Disc to play, I guess this is not the time
