A Submission for

Trail of Cthulhu

Commoriom

"I have yet to translate the terrible and

abominable legend telling how a certain doughty

citizen of Commoriom returned to the city after

its public evacuation, and found that it was

peopled most execrably and numerously by the

fissional spawn of Knygathin Zhaum, whichpossessed no vestige of anything human or even

earthly" ! he #amily ree of the $ods, Clar%

&shton 'mith

The protagonists are members of an expedition to

excavate an ancient settlement buried beneath the

Greenland ice. Faced with conflict from within and

without, and the threat of approaching winter, the

expedition degenerates into a struggle to survive as

the team members realise that the real horror is

beneath the ice under their feet. And the greatest

horror of all may be truth itself.

This scenario is inspired by the Hyperborean Cycle

stories of Clar Ashton !mith, particularly The

Testament of Athammaus andUbbo-Sathla. "t is

recommended that the #eeper reads these short

stories before running this scenario. The story of

the $athieson %xpedition is told in the Call of

Cthulhuscenario Trail of Tsathogguaby the late

#eith Herber and published in the supplements

Trail of Tsathogghua, &'() and The Compact Trail

of Tsathoggua, &''*.

The Hook"n &'+, an archaeological team from $isatonic

-niversity found evidence of an ancient settlement

beneath an ice cap in a remote valley in the

mountains of est Greenland. The protagonists are

members of a &'/& follow0up expedition to

excavate the site.

The Horrible TruthThe site is the ruin of Commoriom, the first capital

of the lost civilisation of Hyperborea, which thrived

before the last ice age. %ntombed in the city is a

dormant, monstrous race descended fromTsathoggua and an alien crystal that grants visions

of the disturbing origins of life on earth.

The SpineThe team members voyage to Godthb, where theycan confront a Rival Expeditionfrom Germany.

They then begin their arduous overland tre in

Evighedsfjorden. Tensions increase between%thelrod, the team leader, and Granger, who is

struggling to conceal his alcoholism, leading to The

Death of Ethelrod. From %thelrod they can ac1uire

a dictionary of the lost Tsath-Yolanguage.

The team receives A Call for Helpfrom the crew

of the German base ship, which has lost contact

with the overland team, giving the protagonists a

moral dilemma.

2uring their 3ourney, the characters find evidence

that strange %simo are watching them and may

discover Gravesof members of the Germanexpedition, apparently attaced by an unnownanimal. A text in their possession, when translated

with %thelrod4s boo gives hints about the history

of the site.

Arriving at the Site, the protagonists find a Cube-

Shaped Struturewith walls inscribed with a

history of the pre0humans who first settled there.

5earby, the remains of the last members of the

German expedition can be found. 6n the valley

floor, a Shado! "nder the #eis visible.

They are harried by frea weather conditions and

attacs by a mysterious$east of the #e Sheet,

which continue until they lin it with the clan of

strange %simo that has been following them, and

neutralise it.

Exavating the Struture under the #e leads to

the discovery of an ancient tower entombed in ice.

2igging into The #e-Cho%ed stair!a&uncovers a

frie7e describing a history of Hyperborea and

eventually leads to a Cit& "nder the #e. "n a vaultunder the ruins of a library is a crystal that can send

the mind bac in time to the disturbing origins of

life on earth.

As the city4s inhabitants begin to awaen they try to

free their 8Father4, leading to the A!a%ening of'n&gathin (hau). The protagonists4 only hope isto flee.

However, even if they escape, the insight granted

by the crystal may still claim their minds.

Victory Conditions9ictory in this scenario means realising the horror

that lies in Commoriom, and surviving it,

preferably with the site safely sealed.

Antagonist ReactionsThe rival Ger)an Expeditionis not a 85a7i

expedition4 in any official sense :there is no such

thing until the formation of the Ahnenerbe in &'/; especially the

esoterically inclined > believed in occult theories of

the uni1ue :or divine< origin of their ancestors on a

lost northern continent :referred to as 8Thule4 or

sometimes 8Hyperborea4 or 8Atlantis4 a time when

the Armitage "n1uiry is in its formative stages. "n

&'+(, Armitage, Bice and $organ scored a victory

against the 2unwich Horror and soon 2r Albert

ilmarth 3oined them following his encounter with

the 86uter 6nes4 in the hills of 9ermont. ust a few

wees ago, the =abodie %xpedition returned from

Antarctica with stories of unnown prehistoric life

forms and a vast range of mountains dotted with

strange structures.

6n his deathbed in &'+', =rofessor Curtis

$athieson revealed a number of unpublished

secrets about the &'+ expedition to his colleague2r Francis $organ. $organ shared the story with

=rofessor Armitage and soon they were woring

8/13/2019 Commoriom Submission v3,14

with =rofessor %thelrod in %ngland to organise a

follow0up expedition for &'/+. However, in late

&'/, word reached them of a rival German

expedition to the same region planned for &'/& and

their pro3ect was hastened by a year. -nfortunately,

this meant 2r $organ was unable to tae part, but

he persuaded Charles Granger, a veteran of the

$athieson %xpedition, to 3oin.

Running Commoriom as astandalone

This scenario can be run as a standalone adventure

or mar a dramatic beginning to an ongoing

campaign.

The difference is that %thelrod has organised the

expedition with the ?ritish $useum, independently

of Armitage and his colleagues, who may have little

insight into what really happened on the $athieson

%xpedition.

Pillars of Sanity

The dominant theme of this scenario is the dignity

or otherwise of human origins.

6ne =illar of !anity that might be particularly

interesting dramatically is Family. A character with

this =illar will have a firm conviction in the dignity

of their origins. "f Caucasian, they may believe in

the theory of the origins of their ancestors on the

lost continent of Thule. They may have heard tales

of 8blond %simo4 in north0western Canada. They

may even subscribe to racist theories lie the

5ational !ocialists of Germany.

They will use the drilling rig, blasting e1uipment,

on the ice sheet over winter until $arch when the

emergency, a team should be able to reach them

=rofessor %thelrod stresses his 1ualifications as a

hard0nosed scholar not prone to flights of fancy or

bi7arre speculations. However, as the claims of the

recently returned =abodie %xpedition to Antarctica

suggest, the poles may conceal secrets that wouldoverturn our entire understanding of the past. 6n

the $athieson %xpedition there were many things

he experienced that shoced him and caused him to

reconsider ideas about the world. He believes that

what they found in the Greenland ice were remains

of a lost prehistoric civilisation, perhaps hinted at in

Gree myths.
