They look like people, and they talk like people. But they don’t think like people, and they don’t feel like people.
They are unable to feel compassion for mortals, and they are selfish beings, rarely thinking of anyone else. They are volatile and erratic, but not easily harmed, and strike out at each other without thought. When they get agitated, things get broken. And they get agitated easily.
They are always dangerous to be around, even when they like you. They are proud and easy to anger, but you must never go with them.
