There is a place where the bodies of the dead lie exposed for decades, frozen in their moment of death. Hundreds of people pass them every year, and even use them as landmarks. That place is the Rainbow Valley, which lies in the Death Zone on the slopes of Mount Everest.

Imagine someone close to you, someone you trusted, convinced you that they were being followed. Imagine you became so wrapped up in their paranoia that you followed them into dangerous situations without question, until finally someone got hurt, and it was revealed to you that it was all a delusion caused by mental illness.
