Well, it's taken from what the Animus said. So while it's partially true, there's also need to interpret somewhat. They 'delivered' changes that seemed most suitable.

[Wizards, she's a little familiar with the idea, but not much. I don't think they're very prominent in the East in the series.]

It wouldn't be as simple as being able to cast the right magic though. They said they tried to deliver properly, so I'm thinking the changes, if any, are with the people's personalities and maybe even home worlds in mind. Would you prefer to have changed, or have things this way?
