Sarpenthyn are a family of animals, more populous in western Roshar where highstorms aren't as strong as they are in the east. There are small sarpenthyn in Jah Keved.


One type of sarpenthyn, observed by Shallan and Adolin in a caged menagerie, is described as being " ... a lump of flesh with two bulbous eyes and four long tentacles." After touching it, Shallan affirms that it is warm-blooded.[1]
