Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
Part of a UA/CoC crossover. Great Old Ones as Archetypes. Mordiggan is the Consumer of Corpses and Keeper of Secrets.
Avatar: The Ghoul (Mordiggan)
The Ghoul is the inhabitant of the graveyard, the eater of the dead,
companion of maggots and the keeper of the secrets of the grave.
Avatars of Mordiggan seek dead flesh, dead knowledge, and secrets best
left buried. They drag skeletons from their closets and crack their
bones for the marrow of their lives. They dress in funeral weeds and
fashions decades old which smell of rot and mildew. At low levels, they
resemble the dead upon which they feed. As they advance, their teeth
grow sharp and doglike to rip and tear the corpses of men, and their
nails grow into hard claws with which to desecrate graves and disturb
the rest of those within. Their Bite and Dig skills must be at least
equal to their Avatar rating to remain in Mordiggan's favour.
At least one human corpse must be consumed for every advance in the
Avatar: The Ghoul rating. The Avatar rating is also the percentage
chance that anyone encountering the Ghoul will perceive them truly as
an undead monster rather than mistake them for a fellow human.
Ghouls gain access to a unique language at a skill equal to their
Avatar rating, which sounds like gibbering and meeping sounds to the
uninitiated. No non-Ghoul can learn this language by mundane means;
eating the dead causes specific changes in the linguistic centres of
the brain, by a process akin to Kuru. It might be possible to learn it
magickally.
As long as the Ghoul continues their unnatural diet, their aging is
slowed by a fraction equivalent to their Avatar: The Ghoul skill. An
Avatar with a rating of 90% would age at 1/10th the normal speed.
Mordiggan is not a jealous God, for all people and things die, are
buried and come to him as food. Even the Archetypes are thrown down to
become meat for the maggots when the fleeting beliefs of humans shift.
A ghoul may preserve (but not advance in) a single other Avatar skill
of 50% or below from the times when they still walked among the living,
provided that it does not exceed their Avatar: the Ghoul skill.
Taboos: expressing preference for the present or the future over the
past (eg: preferring the living to the dead; Eating fresh food rather
than rotten; preferring current rather than former fashions, manners of
speech, etc). Killing other than in self-defence - Ghouls should wait
patiently for the gift of Mordiggan. Consuming the dead is a sacred
trust, not a wanton indulgence to be hastened with violence.
Possible Avatars in History: H.P. Lovecraft Masks: The works of Clark Ashton Smith; "Principles and Parameters" by Meredith L. Patterson.
1-50%: Walking Corpse: The Avatar increasingly resembles a corpse, and
gains some of the unnatural resistance of the walking dead. On a
successful Avatar: The Ghoul roll, the damage done by firearms (and
other weapons relying on sudden system shock rather than massive
trauma) is reduced by a percentage equal to the Avatar score.
Vulnerability to heat and cold is also reduced.
51-70%: Instruct the Worm that Gnaws: By consuming a moderately intact
brain of a dead body and making a successful Avatar: The Ghoul skill,
the Ghoul may access the memories of the dead. On a critical success,
the memories are retained permanently. Otherwise, they fade within 24
hours. To find a specific piece of information, make another Avatar:
The Ghoul roll. A critical failure results in the Ghoul being possessed
by the person whose memories they are attempting to consume.
A special exception is made for the learning of dead languages, for
this is an activity Mordiggan looks upon with great favour. A dead
language is always retained permanently by the ghoul, and can be
learned from even the tiniest scrap of brain tissue. For a language to
be dead, it must once have been a first language of a group of people
(so artificial languages don't count) and there must be no living
person (ghouls and other undead excepted) who speaks it with
conversational fluency or better (so Latin and Greek, still spoken by
many scholars, are out). Being the first ghoul to learn a dead language
causes rapid advancement in the path of the Avatar, and so many ghouls
will seek out long dead corpses from forgotten civilisations, or the
last members of almost extinct ethnic groups, and wait patiently for
them to die, like vultures or, well, ghouls. Teaching a dead language
to a living person breaks taboo. Performing a specific translation
might not, depending upon the purposes of the translation (Publication
is right out - Secrets are to be learned, but then kept).
Digging into the Grave and into the Brain is also digging into the
Unconscious. On a successful Avatar roll, the Ghoul can find the places
deep within their warrens that lead to the caverns of the Dreamlands,
and enter therein.
71-90%: Dead Man Walking. On a successful Avatar: The Ghoul roll, the
Ghoul can take on the seemingly living form of any dead person whose
body they have consumed (more than 50% of the body must have been
eaten). A fresh roll must be made every 24 hours to maintain the
illusion. To successfully fool someone who knew the living person
requires a second roll. This does not affect security cameras, etc, but
does affect the person viewing the footage. A security guard watching
over a CCTV would be fooled, but an automated/computerised facial
recognition system would not be.
91-99%: Skeleton in the Closet. Everyone has secrets we wish to keep
dead and buried, but Mordiggan is the lord of all dead and buried
things. By simply touching someone (living or dead) and making an
Avatar: The Ghoul roll, the Ghoul knows one secret that the person
wishes to keep. The most deeply buried and personal secret will be
learned FIRST.
At 91-99%, the Avatar becomes a Greater Ghoul, growing huge, apelike
and maggot-fat on corpses. It is impossible to mistake them for a human
without use of the Dead Man Walking power or similar Magick.
The current Godwalker of Mordiggan is believed to live beneath the
great cemeteries of Paris and to have gained the post during the Black
Death. It is rumoured that he/it can command the dead to rise and form
an unstoppable zombie army, bringing joy to the hearts of Romano fans
and fear to everyone else.
