The Curse of Yig

Yig is a snake god. The narrator is trying to make a connection between the Quetzalcoatl and Yig, so he travels to an asylum to find out more about the belief. 

There are two unexpected things he finds there. One is a creature living in one of the rooms there. The doctor and two attendants take care of it. The other is a story of how it came to be there.
