The Grave Thorn was a type of crooked tree that grew on the planet of Dathomir. The Nightsisters hung burial pods to the woody barbs of such trees.[1] Grave Thorn could grow to be really big, at which point it would begin wrapping around structures.[2]
Behind the scenes
Grave Thorns first in the Star Wars: The Clone Wars season four episode "Massacre," released on February 24, 2012.[3]
