Siskis are tiny, bright-eyed, highly intelligent creatures found in Mid Wood, in Topaz territory. Due to their small size, they easily become prey to the Wenn, and are therefore going extinct.
Doran described Siskis as bright-eyed, highly intelligent creatures found in Mid Wood, in Topaz territory. With the rise of the Flesh Python population, due to the extinction of Topaz dragons, Siskis were quickly becoming endangered. 
Not much is known about the appearance of a Siskis, other than that they are described as tiny, bright-eyed, furred creatures with dexterous paws. When angry, Siskis have the ability to puff up their fur to make themselves appear larger and fiercer.
