Operation Sun Shower was a military initiative created during the Cold War by House Ulgo. It involved the use of baradium detonator against House Thul. To cover their plan, this Alderaanian family used Killiks against Thul mines to distract them from this planned operation. To secure its transportation, an elite group of Ulgo soldiers that were former Republic Special Forces were used to transport the detonator to the site. Stanel Thul learnt of the plot and tasked an agent from the Sith Empire with dealing with this threat.
