Well, she's on her way to Tenjik to get an old book. That's very, very far away. Wow!
Could very well be another of Estelle's elaborate lies, but hey, it could have been Murayama making a Western Continent reference. Gordius turned out to be an actual location, but as I've discussed in another thread, Suikoden V's Falena may not be 100% accurate to Murayama's vision. That name may have just been an easter egg decided on by the game's staff.
