do i really need to explain what being human entails? they aren't special, they can't do anything with magic, they can't change forms, manipulate the elements, don't turn into huge sized wolves, and certainly don't drink the blood of others. they are NORMAL and the very definition of it. they get sick quite often, they get hurt with the smallest things, are considered emotionally unstable and to the royals are total trash. must i say anymore?
They are mortal, they age, and will eventually die. I'm sure everyone knows this.
Sickness, Famine, Injury, Disease, Hunger, Thirst and anything that will cause a human's quality of life to go far below the normal standards.
