The rawa tukump, the 'spirits of rot', are the spirits of Maring who died of sickness or of causes other than warfare. They occupy the low ground, the wet and fertile country below, and stand opposite the red spirits of the high forest in the Maring scheme of complementary opposites: cool against hot, soft against hard, moist against dry, growth and decay against fire and war. Falling within the domain of Koipa Mangiang, they are bound up with the fertility of gardens, the increase of pigs, and the regeneration of life out of decay. Sources sometimes treat them together with the other beings of the low ground, and the boundary between the ancestral spirits of rot and the wider spirits of the low country is not sharply drawn.
