Lampads protect dark, isolated underground areas from danger and despoilment. In addition, they also act to guard surface-dwellers from the dangers found underground, and guide lost travelers to the surface. Lampads are known for their mercurial and emotional natures; due to the long periods they spend alone underground, they are often highly morose and prone to disconsolate crying, although this process acts a form of catharsis and lampads typically experience relief and calm after a long cry.
Lampads are named after wisps of magic light that they carry, which they use to guide lost travelers to safety and threats to their doom.
