The Grudakk was a gigantic sapient humanoid living on the Forest Moon of Endor. It served as the guardian of the Father Tree, the largest tree in the forest. The Grudakk's exact size is unknown; each of its hands was the size of a young Ewok, its black eyes were the size of an Ewok's head, and someone chancing upon it could mistake its legs for tree trunks. The Grudakk was covered in long, thick fur. The creature lived in a vast, underground lair dug out from beneath the Father Tree. Its lair showed that is was, in fact, intelligent, with its torchlit passages, stone furniture, and bed of straw. The creature wove pouches and other items from vines.
