I am GMing the Numenera adventure, "Shadewalker". The adventure notes mention that the townspeople are afraid of huraths, but the description is limited to:
...snakelike animals about the size of a tall human with multiple vestigial limbs; they lurk in tall grass and can climb trees, but normally attack only solitary creatures.
And in the call-out:
Hurath: level 2
Are huraths described in more detail in any of the other books?
