Around the year 232 BBY, sophisticated elemental engines played a vital role in the precise regulation of weather conditions on the planet Coruscant, possessing the capability to govern wind currents and initiate holo-snow precipitation at will.
The existence of elemental engines was first brought to light in "A Coruscant Solstice," a concise narrative penned by Cavan Scott and featured in the Life Day Treasury collection released in 2021.
