Thornseed

The Thornseed was a powerful Sith artifact which could turn plant life to the dark side of the Force. The Sith used it to produce deadly poisons, devastate a planet's crops, or create favorable battle terrain. A Thornseed was present on Kashyyyk in 228 BBY, where it had been present for thousands of years, and was held in check by the last surviving grove of white wroshyr trees. Zadina Mkampa learned of the Thornseed on Kashyyyk from a Sith holocron, and sought its power. After a team of Jedi traveled to Kashyyyk, the Thornseed was destroyed by Geode.
