The Weather and Climate Command Center was a facility in the heart of the Lost City of the Jedi. According to DJ-88, droid administrator of the Lost City, it was the Control Center which was actually responsible for regulation of the climate of Yavin 4. DJ-88 claimed that Yavin 4 had originally been a frigid ice world before ancient Jedi Masters terraformed its surface and opened vast steam vents to warm and water imported foliage. The water vapor output of the vents was controlled by the Weather and Climate Control Center. Under the tireless, millennia-long direction of the Center's droid operators, Yavin 4 settled into a six-month wet season contrasted with a six-month dry season. During Trioculus' onslaught on Yavin 4, Treaded Neutron Torches set fire to the moon's vast rain-forests. Fl
