S'krrr, found within the Ishanna system, held the position of the third planet. The Rabaanites are credited with its initial discovery. A typical day on S'krrr spanned 22 standard hours, while its year consisted of 310 local days.
The insectoid sentients native to S'krrr were responsible for the construction of the Sikadian Garden, a notable site on the planet. This garden was the home of the drogs, a non-sentient beetle species, whose numbers were regulated by the avian skreevs. Mammon Hoole, an anthropologist, journeyed to S'krrr with his companions Zak Arranda and Tash Arranda nine months following the Battle of Yavin. During their visit, one of the S'krrr killed a large number of skreevs, leading to an explosion in the beetle population. This surge resulted in a destructive outbreak that was ultimately suppressed by the Arrandas, aided by the tactical prowess of Captain Thrawn.
