The Festival of Nida's Rise marked a significant holiday for the Lost Tribe of Sith people, observed on the planet of Kesh. This celebration occurred on the specific day commemorating the rise to power of Nida Korsin, the second Grand Lord. Held every seventy-nine years to mirror Korsin's time in power, the event featured a large-scale festival near the Grand Lord's palace, lasting a full month. Notably, in 3000 BBY, the festival coincided with Testament Day, a holiday held every twenty-five years to remember the death of Yaru, Korsin's father and the initial Grand Lord of the Tribe.
