Sky Torch

The Sky Torch was a weapon designed by the eccentric Doctor Nasan Godera, one of the Galactic Republic's chief scientists. Godera began the project sometime before the Great Galactic War with the Sith Empire, as he resigned his position of Chief Designer at the Republic's Advanced Development Laboratories in disgust when the Republic accepted the Treaty of Coruscant in 3,653 BBY.

Behind the scenes
The Sky Torch was first mentioned in the 2012 reference guide Star Wars: The Old Republic Encyclopedia, in the entry for Doctor Godera as part of a list of his weapon projects, though no information was given on the device's capabilities.
