The Devanu have always trained and controlled creatures to do their will. Once they used the Fubarnii to create weapons and magnificent towers. While the very abilities that were useful in the Fubarnii eventually led to the downfall of the Devanu, there are other beasts still used for simpler, more violent purposes.

The Grishak have been used by Devanu for many generations, since before the rise of the Empire, and are still employed by most Devanu tribes. They have been bred as efficient hunting beasts that run silently besides their masters, and are trained to respond to the Devanu cries, ploughing into their targets with a terrifying screech, dragging down their victims with their powerful jaws, finding cracks in armour and tearing flesh from bones.
