#lekhoet

There are lots, but I will only share the ones I have decent sketches of. 

Lekhoet

The Yaschtkin (goblins) have a legendary creature named Lekhoet who lurks deep in the forest and lures children in to eat. He is a trickster who masquerades as a beautiful pale-faced prince, but his true form is a lizard-like beast. What makes him so insidious is that after he is sated and has finished eating a child, he produces a duplicate of that child from underneath his cloak. The duplicate then goes to the child's family and, after several days, they dissipate into smoke, never to be seen or heard from again.

The Mimim

In the Northern Siens and close to where the Alluneshans once lived grows a carnivorous plant called the Mimim.  The reason it is on this list is because, although it is technically a plant, its sophisticated hunting methods indicate that it is indeed sentient. The most distinguishable elements of a Mimim is its surrounding golden field, and its unusual ability to puppeteer a character fashioned out of spurs. Many survivors of the flower claim that the Mimim constructed the image of a little girl that lured victims in by claiming she was lost. The deception would draw its prey close enough for the spurs to grab them and throw them into the flower's mouth.

Sand Striders

In the Ottoneshan deserts, there are native creatures called Sand Striders, or in the local tongue, "Pezelshan". These massive creatures are completely blind but detect everything through vibrations and heat sensory.  When they travel through the sand, it appears as if they are gliding or slithering with little effort, which makes them the fastest desert creatures on record.  The Ottoneshans recognized this and so they bred and tamed them for war.  Only the most elite of soldiers are given the honor to ride these majestic creatures. 

Thanks for the question, anon!

And have some bonus concept sketches of...whatever the hell these are-
