The devanu have always trained and controlled creatures to do their will and the grishak have been used by devanu for many generations, even before the rise of the Empire. In those times many devanu masters selectively bred grishak to be bigger, nastier hunters who immediately obeyed their commands. When the devanu were scattered those grishak bred with the wild beasts, dominating them and leaving pockets of these savage beasts that even now cause problem for the remote regions of the Empire.
Jenta:
All but the youngest of the grishak hatchlings will join in hunts, often working as small groups accompanied by an older sempa, or even a kopa. While not as powerful as the older grishak, they are still very dangerous creatures!
Sempa:
Grishak sempa are the hunting beasts most commonly used by devanu tribes across the Empire. They are efficient hunting beasts who can be quickly trained to respond to the devanu cries, running silently besides their masters until instructed to charge, at which point they plough into their targets with a terrifying screech, dragging down their victims with their powerful jaws, finding cracks in armour and tearing flesh from bones.
Kopa:
Some grishak survive countless hunts and mature into kopa, leading the younger grishak and inspiring them to work together as a deadly pack.
In the wild, an established Grishak pack will have several kopa and this structure is often maintained when the pack is led by the devanu.
