The xiezhi is one of the few among the Guardians who did not go mad in the course of the First War and remained in the human world. They’re rare – they always have been – and seeing one tends to be a significant experience because of their reaction to injustice.
If they see what they consider to be injustice, they will, without fail, attack the villain without mercy, goring with its single horn, then devouring.
Their appearance lands somewhere between a lion and a dragon, and their colors range from grey to gold. They have one horn in the center of their foreheads.
