Fera are beasts with powers and abilities that are both powerful and abnormal. They can come in any shape, size, color, and form. So, they could be a small little ugly doglike creature, or giant humanoid creatures the size of buildings. The most common size or height for them is 7’6ft-9’3ft. Hybrids are half human, half fera people. They’re able to transform from human to fera at will, and vice versa. That’s all the information you’re getting from the discription.
