Area for Samurai and Ninja

[Elexia]

But in all seriousness. Now I'm curious. Is there really no other information about this place in the game's lore?

There's a lot missing from the game's lore. This is why I loved how they handled it with XI that lacked some in-game explanations but still linked. (Vanadiel Tribune, A lore book released prior to WotG iirc.)
