Unidentified Republic superweapon

The title of this article is conjectural.

Although this article is based on official information from the Star Wars Legends continuity, the actual name of this subject is pure conjecture.

"What has it to do with this? Very simple: that solar flare was not a natural disaster, Doctor. The Republic, the glorious, wonderful, benign Galactic Republic's military leaders were testing a new weapon. A planet buster, a superweapon for some kind of ultimate battle station being developed. They fired it into our sun, and they miscalculated. They had a base on our moon, the scientists and military who'd created this abomination. The flare got them, too. Small comfort to me and the few Equani who were offworld when our planet was murdered."

In 23 BBY, the Galactic Republic tested a superweapon on the star Nharl. The resulting intense solar flare accidentally destroyed all life on Equanus, as well as the superweapon and its testers. Only those Equani offworld at the time survived. Equani scientists realized too late that Equanus was being destroyed, and the planetary comm lines were jammed with Equani saying their last goodbyes to each other.^[3]
