Henku were large, warm-blooded mammals thought to be related to the banthas native to the desert planet Tatooine. Similar to banthas, these creatures were raised for their milk, meat, and leather, and they also had distinctive curled brown horns. With their thick black skin and dense white fur, henku were well-suited as livestock on cold planets like the snowy, mountainous Kijimi. On Kijimi, fishers commonly utilized henku as pack animals to move supplies between lakes and settlements such as Kijimi City.
