The probability field associated with these memetic 
agents restricts the typical phase space associated with 
thought processes. It is believed that when the geas is 
broken in a way which does not involve the removal of 
the memetic agent and thus the probability field, the 
uncontrolled "release" of the cognitive phase space 
results in uncontrollable neural activity. This rapid and 
erratic neural activity often causes a grand mal seizure in 
the subject, followed by the possible total collapse of the 
lungs and cardiac arrythmia as the memory purges the 
memetic agent, which interferes with unconscious 
nervous activity... 


— Excerpt from "Cuchulainn syndrome: The collapse of 
the probability field and its effect on human health", lyer, 
R., Vidyasagar, R. 


Prometheus Laboratories' early adoption of contractual geas and 
memetic technologies in general allowed them to observe the first 
recorded case of Cuchulainn syndrome in 1965. To this day, 
Cuchulainn syndrome remains one of the most hazardous obstacles 
to the safe implementation of contractual geas. 


The condition which would come to be known as Cuchulainn 
syndrome was initially observed in a Prometheus maintenance 
worker named Kieran Carson. Colleagues reported he was unable 
to do his job without suffering seizures and muscle spasms. 
Investigation showed that he was, in fact, infected with a memetic 
agent he had unintentionally been exposed to during his time 
working for Prometheus. This memetic infection forced him to 
unintentionally break his geas by contravening a clause in his 
employment contract. 


Using anti-memetic treatments pioneered by lyer and Vidyasagar, 
the memetic infection was removed, followed shortly thereafter by 
the geas carrier. In order to treat the after-effects of the syndrome, 
another geas was placed on Carson which prevented these spasms 
from occuring by making these random neural misfirings impossible 


for him to perform. 


The Kaliningrad Geas Standard 


Following the discovery of Cuchulainn syndrome, in order to ease 
treatment of these cases, representatives of various occult 
organisations including the Foundation, the Global Occult Coalition 
and Prometheus Labs gathered in Kaliningrad to discuss this matter. 
It was decided that an international standard for geas should be 
created, encompassing the memetic carriers and probability fields 
used in the creation of geas. 


The agreement resulted in the Kaliningrad Geas Standard, an 
international specification for geastechnology used in various 
applications. This specification details the types of memetic carriers 
and probability fields acceptable for use, with an especial focus on 
contractual geas. The majority of normalcy preservation 
organisations have adopted this standard for the purposes of easing 
Cuchulainn syndrome treatment — however, it is not uncommon to 
see non-standard geas being employed in regions without access to 
the technology required to fabricate the memetic agents specified. 


The Fall of the Setanta 


The most crushing blow to geastechnology and the reason for its 
infrequent usage today was the Setanta incident. In 1968, the 
proposal for a geas-based medical alert system was initially 
submitted, involving a central hub satellite managing the creation 
and updating of these geases. It was hoped that this system would 
increase the survivability of medical conditions such as strokes by 
ensuring rapid response and also increasing the life expectancy for 
patients with debilitating illnesses. 


The Setanta was launched on May 5th, 1972 and successfully 
managed this system for 9 years. On July 19th, a meteoroid collided 
with the Setanta; the meteoroid's high velocity resulted in it disabling 
the radio communications array of the satellite and the disruption of 
the demonics technology used in the Setanta. 


The damage and defacement of these demonic components 
resulted in at least thirty demons being discharged into the rest of 
the electric components, further damaging the satellite and making 
repair operations difficult due to the inadvertent demonic possession 
of the majority of the repair crew dispatched. In a last-resort effort to 
recover the Setanta, Prometheus handed over custody of the 
satellite to the Foundation, who in cooperation with the Horizon 
Initiative and specialists from Prometheus managed to dispatch the 
majority of the demons, although they did not successfully repair the 
satellite's facilities. The satellite is still under containment by the 
Foundation as SCP- 


As a result of the malfunction of the Setanta, over 790 patients 
signed up to the services provided by the Setanta acquired 
Cuchulainn syndrome due to the malformed nature of the geas 
being handled by the satellite. This catastrophic loss of reputation 
Prometheus Astrotechnologies incurred meant that several other 
projects were abandoned due to similar fears.

sitting in SCP-738-3. However, all attempts to observe this entity 
when not seated in SCP-738-2 have failed, and further descriptions 
of the entity are inconsistent between sessions, even with multiple 
sessions with the same person. When asked about this, the entity 
claims to be the same entity each time. Some frequent descriptions 
of the entity include ‘seductive’ and ‘charming’. Sessions with the 
same person that are close in time report similar or identical entity 
appearances. Sessions with different people that are close in time 
report different entities appearances. Descriptions of the voice do 
not match the voice recorded on the equipment. 


Addendum 738-1: History 


SCP-738 was recovered from the office of , a Catholic 
Cardinal, after his death on / / . He had received it as a gift from 
the Pope for extraordinary services from the Vatican archives. The 
Foundation became aware of SCP-738 after [DATA EXPUNGED]. 
With dead and his will contested in the aftermath of the 
event, Foundation personnel acquired the desk. Foundation agents 
in the Vatican reported recovering some of the documents 
surrounding SCP-738.

Maintenance Staff Involved: 


¢ William Dunbar 

¢ Hayley Greene 

¢ DraSko Kumiega 

¢ Foundation Specialist Richard Kowalski 
¢ Foundation Specialist Arjun Jagannath 


Maintenance Location: PSAT Setanta 


Maintenance Performed: Replacement of malfunctioning demonic 
circuitry and lambda wave array, expulsion of demonic entities 


Equipment Allocation: In addition to the tools required for the 
repair of the demonic circuitry and lambda wave array, the 
maintenance team were issued with the following products for the 
purposes of self-defense against possible free demons. 


1. ElDolon (Electrodemonic Interference Device) — The ElDolon is 
designed to disrupt the manifestation of a demon by interfering with 
the interaction of the demon particle with photons, preventing 
demons in the area of effect from manipulating electromagnetic 
forces. 


2. Gell-Mann Delta-metal Embroidered Suit (one per person) — 
Initially produced for the EXORCIST task force, the Gell-Man suit 
contains several warding seals derived from Vedist occult 
symbology embroidered into the suit using delta-metal thread. This 
creates a full-body warding pattern without the need for 
subcutaneous implantation. 


3. Ortiz-Hannigan Geas Operation Device — To be used a last 
resort should any of the team members succumb to demonic 
possession. The application of the geas through proprietary micro- 
memetic agents projected by the device's lens should be sufficient 
to at least immobilise a possessed member, if not prevent the 
demon from acting. 


Results of Maintenance: Maintenance failed to restore the 
satellite's functionality, but prevented the continual malfunction of 
the satellite. The residual demonic manifestations were eliminated, 


making it possible for a second maintenance operation to be 
performed with the aim of restoring the satellite. 


Maintenance Report: See attached file below. 


Upon closer inspection of the problem, it became clear that 
the most advisable course of action was to eliminate the 
possible threat of demonic interference prior to beginning the 
actual maintenance work. Following the successful docking 
of the Connacht with the Setanta, Greene deployed the 
ElDolon so as to ensure the demons would not attempt to 
interfere with the Connachfs circuitry. 


Due to the large quantity of demons discharged, the 
E!lDolon's power source began to run down within minutes. 
Jagannath, the Foundation demonics specialist, suggested 
that a more permanent warding mechanism could be created 
at the docking port, so that the ElDolon's charge could be 
conserved for the bulk of the maintenance work. After 
retrieving his field supply kit, he successfully erected a Type 
IV ward, preventing the Connacht from being demonically 
influenced. 


Dunbar and Kumiega then left the Connacht and the 
ElDolon's field of influence in order to test the function of the 
Gell-Mann suits — the wards held despite the continued 
attack. Greene then followed them with the ElDolon, now de- 
activated to conserve power. Jagannath similarly followed 
Dunbar and Kumiega, while Kowalski stayed behind to 
monitor the status of the ward. 


Kumiega was the first to encounter the corpse of Nielsen (a 
member of the previously dispatched maintenance crew) and 
initially thought he had been reanimated — however, due to 
the demon's relative inability to control the motor functions of 
the corpse, its movements were unnatural enough for 
Kumiega to recognise its possession. After restraining the 
corpse using an improvised set of handcuffs, Kumiega 
navigated to the lambda array and began work. 


It was later found that a fault in the anti-demonic casing of 
the replacement parts had led to the successful demonic 
infiltration of the parts. As soon as the lambda wave array 
was outside of the ElDolon's area of effect, the array 
promptly malfunctioned and overloaded, releasing a final 
high-power burst of lambda waves prior to the destruction of 
the array. After Kumiega realised that the rest of the parts 
would be similarly compromised, he abandoned work and 
instructed the crew to begin repairing the satellite's demonic 
circuitry. 


Continued work was halted following the breakdown of 
Dunbar's Gell-Mann suit due to the abnormally high demonic 
presence in the area. Greene instructed Kumiega to run the 
ElDolon not off battery power, but rather the on-board 
thermoelectric generators. The modification was successfully 
performed and Jagannath attempted to perform a field 
exorcism on Dunbar while Greene began several 
banishment workings to dispel the remaining demons. 


Greene's banishment ritual succeeded, although 
Jagannath's exorcism was interrupted by the opening of a 
microscopic tartarean pinhole. This resulted in the 
spontaneous combustion of several panels and the 
replacement of approximately 20% of the oxygen on-board 
with sulphur dioxide. In an attempt to prevent further 
phenomena from occuring, Kumiega and Greene cooperated 
to destroy the demonic circuit sustaining the pinhole. 


Finally, Kumiega and Greene returned to the Connacht with 
Dunbar immobilised, before they undocked and began the 
process of re-entry. 


Cost of Maintenance: Estimated at roughly $20 million, including 
the cost of the exorcism after landing. 


Payment Details: The Foundation has paid $3 million of this cost, 
with the majority of their share being waived due to their supply of 

personnel for the maintenance effort. The Global Occult Coalition's 
share of the payment is yet to be acquired.

Unicorn Horn 


Lapland, a herd 
of wild unicorns 
— previously 
believed to be 
extinct — was 
discovered. The 
expedition 
leader, Irwin 
Trask, 
recognizing the 
value of these 
beasts, directed 
his party to 
capture the 
creatures and 
had them 
transported back 
to London for 
study. As 
repayment for 
our assistance in 
financing the 
expedition, 
Prometheus 
Labs has gifted 
us three 
breeding pairs, 
along with 
copies of Trask's 
notes regarding 
the animals. 


Historically, the 
unicorn was 
believed to 
posses 
numerous occult 
and paranormal 
properties, 
resulting in its 


being hunted to 
near extinction 
by those 
attempting to 
use the animals 
for ritual or 
medicinal 
purposes. 
Modern testing 
has verified 
some of these 
beliefs; most 
notably, the horn 
of the unicorn, 
when ground 
into a powder 
and ingested, 
reverses the 
effects of sexual 
intercourse. 
More 
specifically, it 
reorders 
physical reality 
so that the 
consumer will 
have never had 
intercourse, 
restoring the 
body (but not the 
mind) to a virgin 
state — and 
incidentally 
curing venereal 
diseases and 
killing any living 
offspring. 


It is my 
recommendation 


that we use the 
breeding pairs 
provided to us 
by Prometheus 
Labs to establish 
a steady supply 
of unicorn horn, 
which can then 
be sold as a 
contraceptive, 
curative, and
