Luo Hou

A legendary colossal beast, natural enemy of the Kun Peng. It is said to be so large it can swallow the sun and moon, and can naturally form independent spaces within its body. The ghost fog is associated with its manifestation. The Yin Underworld Land in the human realm and possibly the Netherworld River Land are speculated to be spaces formed within the bodies of Luo Hou beasts (possibly different individuals). If a Luo Hou dies of old age, the space within its body does not collapse and can exist eternally.
