User blog comment:GoDai/GoDai's Translations: T.U.S., Exis, and Phantaminum (Pentaminum)/@comment-4076672-20120621032340

Well this sort of explains why Zahard and the 10 great warriors brought in weapons, meant for use in vacuum. I was wondering why the hell people can breath in space? It's mentioned here:

Of the Tower's Weapons

So this is a nice theory about how Rachel might've known about the Tower. Like one user on the Batoto forum speculated or stated, it probably takes a lot of knowledge to find out about its existence and so on. If it's in a dead language or something, she gotta learn it. Or research really deeply. There is no way, a commoner can just figure out everything like that.

Or she even knew some Exises? Like some of the other Irregulars?

Anyways, thank you. :)

That there are so many wars taking place,might explain why most or if not all of the Irregulars are fine with slaughtering people. Zahard and the 10 great warriors, Pentamimum, Rachel and possibly the rest of the Irregulars, except for Baam/Viole. Because they grow up in times of murder and they get to imitate the other adults. And loss of a human life is insignificant.
