The descriptions for the interior windows are a bit off... the Triangular Jalousie reads: "A walnut windowsill carved in the traditional Bastokan style."
It IS made of walnut... but it's Windurstian.
Similarly, the Square Jalousie reads: "A rosewood windowsill carved in the traditional Windurstian style." Again, it IS rosewood, but it's San d'Orian.
The Awning reads: "An elm windowsill carved in the traditional San d'Orian Style" (does not have the period at the end, and it's not associated with any of the three nations.) Also, I'm not sure how this window is an awning... it looks more like a Transom (RL) than the Transom (in-game) does.
And finally, the Transom reads: "A mahogany windowsill carved with myriad decorative lines." It is Bastokan.
