It's NOT the Great Desert from Tri/Ultimate though. At least not the same part so it's possible, that Darren is fought in Siki while Jhen lives in the new World. Maybe the Desert is kind of the border between those two (wouldn't be too far off since it'd be difficult to live there and Loc Lac seemed to be in an area that's not too far into the desert)
