Tund

Tund was a verdant terrestrial planet and potent Force nexus situated upon the north-eastern borders of the Open Sea in the Centrality sector. A remote colony world of the Sith species first settled around 27,700 BBY, Tund saw use as a prison for heretics and exiles prior to the collapse of the old Sith Empire, and subsequently came to serve as both the headquarters of the Sith-blooded Sorcerers of Tund and the adopted homeworld of the Toong species. The planet was destroyed in 5 BBY by a biological warhead released by the Croke Sorcerer of Tund Rokur Gepta.

Tund was first discovered and colonized around 27,700 BBY by a group of exiled Sith belonging to the Kissai priest caste. These outcasts were banished from the Sith homeworld of Korriban for interpreting the death of Sith King Adas during the Infinite Empire's failed invasion as a sign from the Force to reject the dark side. Fleeing Sith space aboard a Rakatan ship equipped with a Force-powered hyperdrive, these Kissai followed the Force to the hidden world of Tund in the Centrality sector, remaining in seclusion for millennia.

Later generations of Sith belonging to both the ancient Sith Empire and old Sith Empire used Tund as a penal colony for the imprisonment of their own heretics and exiles. Following the 6900 BBY conquest of Sith space by the Human-blooded Dark Jedi Exiles, Tund's pureblooded Sith were joined on-world by disparate groups of half-breed Sith-Human colonists. While many of these half-breeds were outcasts banished from the Sith Worlds, a number of Sith refugees fleeing the Republic counterinvasion that followed the Great Hyperspace War likewise settled Tund in the aftermath of the Sith Empire's collapse.

These disparate traditions eventually coalesced to form the Sorcerers of Tund, a sect of Sith-blooded Force users who denied the existence of the light and dark sides of the Force. Though these Sith remained isolated on their remote world for millennia, they were joined in 45 BBY by Toong refugees fleeing the devastation of Toong'l. The Sorcerers persecuted their new neighbors, but were themselves rendered extinct by the actions of one of their own. Rokur Gepta, a Croke who had infiltrated the group to learn its secrets, killed the Sorcerers and destroyed Tund with a biological weapon in 5 BBY to ensure their knowledge remained exclusively his, bringing an end to the Sith colony that had persisted for over two dozen millennia.
