Grayskins, or Carriers, are the servants of The Choir. Their name comes from the fact that they are covered in the gray fungal form of the Choir. Most Carriers are unwilling slaves, constantly tormented by the noises the fungus produces. In order to disguise themselves, they often wear heavy clothing over most of their body.
Grayskins will die within a few weeks of being infected, and the fungal Choir will leave the corpse. This has been theorized to be a method of reproduction for the Choir. Fire is often brought up as a means to slay a Grayskin.
