Given time, the bogs accrue the negative and tragic energies of these dead, transferring these energies to those sunk into their muck and ooze. And eventually, a tipping point is reached, and the bog mummies may arise to stalk from the muck in search of some retribution.
Bog mummies are characterized by their tough, leathery flesh, well-preserved in the anaerobic and acidic environment of the bog bottoms. The mummies will be tannin-stained to a dark red-brown. Many will bear evidence of their means of death or maltreatment and torture prior to death - nooses, manacles, lacerated flesh. Well preserved, the bodies may appear fresh-dead, but for these ghastly features.
An individual mummy, upon arising, will have a target of its revenge - typically the source of its misery and death, whether it is a magistrate, shaman-priest, or members of the lynch mob. For those who have been interred long enough, their original tormentors may too have crossed the veil. For these, they will seek a member of the same class, or perhaps a descendant of their original killers. The mummies will resolutely seek out their condemners, and are a bane in areas where sacrifice and justice are meted out in the bogs.
