Something That Should Be Long Dead.

The posture of these beasts doesn't look pleasant. Their current posture restricts freedom of movement apart from the less obvious pain from the stretched limbs. When this observation is combined with the sight of chains that forced them into this unpleasant position, it is safe to say that the beasts are imprisoned. 

A voice said to him, "Don't be shocked. This is just a prison for Warrogs."

The speaker even chuckled at him. 

He turned to the source of the voice. He saw a large Warrog beast that dwarfed him. This beast has black and red fur. It also has two black horns, black claws, and black exposed canines. Its eyes are trained on him right now. 

All the prisoners are Warrog beasts. They have different shapes and sizes. They also have a different number of tails. The one that spoke to him just now is one of the smallest. But all of them have black horns and black claws.
