The Banuk believe that each machine has a song, and that they were all docile before something turned them against humanity. The Banuk claim that with the coming of the derangement, there was a change in the 'machine songs' of the 'machine spirits', suggesting that these have become increasingly discordant. According to the Banuk shaman Siluk, significant events are taking place within Ban-Ur due to disagreements between hunters and shamans about how to respond to the changes in the world. As a result, many shamans have been exiled from Ban-Ur.
