It will be even more accessible when the earth is cleared off in anticipation of the

and one scholar has said that it is identical with the lost city of Yian-Ho.

INNSMOUTH. 1) Massachusetts town at the mouth of the Manuxet River. At
one time the town was a thriving seaport, but today it is almost deserted.
Innsmouth was founded in 1643, quickly becoming a major center of com-
merce upon the Atlantic due to its large harbor. Ships from this town sailed all
over the world, bringing back goods from many ports of call.
During the war of 1812, the captains of Innsmouth turned privateer and
attacked the British fleet. Half of Innsmouth's sailors perished during skirmishes
with the enemy, marking the end of the town's prosperity.
After the war, Innsmouth's revenue came mainly from the mills built on the
banks of the Manuxet and Captain Obed Marsh's successful trading ventures
T H E C T H U L H U M Y T H O S ENCYCLOPEDIA
I N N S M O U T H L O O K T O A N I N V E S T I G A T I O N . . .
in the Indies. Around 1840, Marsh lost a source of the gold upon which he had
depended, and the town's economy spiralled downward. It was around this time
that Marsh began the Esoteric Order of Dagon, a cult based on a combination
of Scripture and the beliefs of the Polynesian islanders Obed Marsh had visited.
Some whispered that Marsh's Order worshiped darker gods, and the Order's
nocturnal trips to Devil's Reef are legendary.
1846 was the year of the Innsmouth plague. The exact disease responsible has
never been identified, though it might have been a malady brought to the town
on one of the remaining traders. What precisely happened during the plague
remains a mystery, though evidently rioting and looting were widespread. When
visitors from neighboring villages arrived, they found half of the town's people
dead and Obed Marsh and his Order in firm control of the town.
Despite Innsmouth's curious newfound wealth in fishing and gold refin-
ing, the town's fortunes continued to decline. Also, degenerative traits began
to turn up in the resident's children, most likely the aftereffects of the plague.
During the Civil War, the town was unable to meet its quota of draftees due to
these widespread deformities. Innsmouth remained under the Marsh family's
rule for many years and over time became shunned by the people of the sur-
rounding countryside.
This state of affairs continued until 1927, when the government launched
an investigation into supposed bootlegging taking place in the town. This in-
quiry culminated in a raid in mid-February, 1928 (though one source places
it in early summer), in which Federal Agents dynamited many of the town's
abandoned buildings, disbanded the Esoteric Order of Dagon, and removed
the bulk of Innsmouth's population to military prisons. Rumors persist that
a submarine fired torpedoes off of Devil's Reef at an unknown target. The
Innsmouth residents remained at the camps until the Forties, but rumor has
it that many are still kept at secret government facilities.
Accounts of Innsmouth after this disaster have become muddled. It might
have become a ghost town, the home of an innovative software company tak-
ing the industry by storm, an abandoned area under military quarantine, or a
tourist trap filled with historical exhibits and ghastly museums.

[Innsmouth first appeared in Lovecraft's "Celephai's", but in that story it was
placed in England. Lovecraft later used it in "The Shadow over Innsmouth",
and later authors have set it there as well.]
I N N S M O U T H LOOK. Hereditary condition taking its name from Innsmouth,
Massachusetts, where the majority of the population possessed this malady.
An infected person seems normal at birth but undergoes a slow, debilitating
metamorphosis later in life. These changes often begin between the subject's
twentieth birthday and middle age, though sometimes the disease's effects may
be noticed earlier or later.
A person affected by the Innsmouth look is characterized by large, bulging
eyes, scaly and peeling skin, flattened nose, abnormally small ears, partially
webbed fingers, and a wattling around the neck. In the later stages, the bone
structure of the skull and pelvis shifts, forcing the victim to adopt a slow,
shambling gait. The most advanced cases may involve the development of
what appear to be rudimentary gills in the subject. Usually strange dreams of
underwater realms and a growing obsession with the ocean accompany these
physiological mutations. Often, the person with the look drops out of sight
after having the condition for many years; presumably, the sense of self-pres-
ervation is overridden by their desire for the water, and they drown themselves
while answering this call.
Sometimes, a person with the Innsmouth look will progress only through
the early stages of the malady, remaining in this state for the rest of their lives.
The exact cause of this is unknown. Also, proximity to the ocean or certain
artifacts has been known to trigger the change in seemingly healthy individu-
als, though more research is needed before these factors can be predicted with
any degree of certainty.

IOD. Being which is partly animal, vegetable, and mineral. Iod came down to
earth in the days of our world's youth. He was worshiped in Mu as the Shining
Hunter, and the Greeks and Etruscans knew him in the guise of Trophonius and
Vediovis, their respective gods of the underworld. Beings beyond the farthest
galaxies revere him as Iod the Source.
Some wizards have been able to summon Iod to do their bidding. Such
conjurations are perilous, as the entity may hunt the wizard in order to devour
their soul if not properly contained. No known volume contains the complete
ceremony for calling up Iod, however.

IREM (also IRAM or UBAR) Lost city somewhere in the depths of the Arabian
desert. Irem is the City of a Thousand Pillars, and is called "many-columned"
in the Koran. That text states that it was destroyed because of the sins of its
inhabitants.
Various myths have been told about this city's origins. One tells of Iram
being built by creatures of great size and colossal strength. With our knowledge
of the creatures of the Mythos, this should not be lightly dismissed.
Another tells of Shaddad and Shaddid, two brothers and the joint rulers
of the great city of Ad. After they had ruled Ad for a time, Shaddid died. Fol-
lowing this tragedy, Shaddad became more egotistical, deciding to create an
imitation of the celestial paradise on earth. He gave orders to build a great city
and garden in the desert of Aden, and named this new paradise Iram, after his
great-grandfather Aram. When the garden was completed, Shaddad traveled
with his entire entourage to view his new creation. A day's journey from the
site, a "noise from heaven" destroyed him and all his courtiers.

This is hardly the only tale of the city's destruction. Some tell of creatures
from the sky, who remain in the city to this day, killed or drove out all of the
g a r d e n ' s inhabitants. Some have said that Irem was actually built by minions
of Shudde-M'ell, who had the city destroyed due to its inhabitants ignoring his
c o m m a n d s . Still others believe that the men from Irem journeyed beneath to
fight the creatures from the Nameless City who ate their inhabitants.
Abdul Alhazred opened up the first gate to allow the Great Old Ones' min-
ions into this world in the ruins of Irem. Ludwig Prinn placed the beginnings of
the cult of the worm-wizards in these ruins, and some suggest that an inhuman
"Supreme One" who dwells here sends out orders to the cults of Cthulhu around
the world. Travellers lost in the deserts of Arabia have been known to stumble
upon this city, later bearing their delirious tales back to civilization.
Over the gateway to Irem, a tremendous hand is carved, which is said to
reach for the artifact known as the Silver Key. A myth much like this is connected
with the Alhambra in Granada. When a carved hand above a doorway in that
palace grasps a long-lost key again, the palace will be instantly destroyed. This
might have derived from an older myth relating to Irem. Seekers after wisdom
on this and other points might seek the witch I'thakuah in the caverns beneath,
provided she does not strangle them first.
[The actual ruins of the city of Iram, or Ubar, were found in 1992, though
some scholars dispute this identification. Those who hope for a thousand-pil-
lared city will be disappointed, as it seems to have been only a small fortress
surrounded by tents.]

ITHAQUA (also WIND-WALKER, DEATH-WALKER, and WENDIGO).
Great Old One whose domain includes most of the northern regions of Earth.
Ithaqua appears as a tremendous anthropomorphic shape with glowing red
eyes and webbed feet that walk through the air as if on solid ground, or as a
cloud of mist or snow with eyes. The Wendigo often emits eerie howling noises,
but seeing the creature is worse; any that gaze upon Ithaqua are doomed to
be taken by him.
Like many of his fellow Great Old Ones, Ithaqua seems to be limited or
imprisoned in a certain area. It originally rested beneath a plateau on the world
of Borea, until it was able to escape. (Much of its lifeforce may still be held in
the Temple of the Winds at the North Pole, which only appears on the night
of the winter solstice.) On our own planet, Ithaqua is unable to leave the area
between North Manitoba and the North Pole, though in certain circumstances
the Wind-Walker may travel further into temperate climates. Whether Ithaqua
may also manifest itself in the Antarctic is uncertain, as few humans have spent
much time in that region. Ithaqua is not confined to our own world, however;
it possesses the ability to fly through space, and is known to travel often to the
world of Borea. The Great Old One returns from its journeys elsewhere to earth
for one year in every five, when his cult experiences a stunning revival among the
peoples of the north. Those in warmer latitudes who consider themselves safe
from the Wind-Walker's wrath should beware, however; the Arctic boundaries
do not constrain the servitor winds and other minions of Ithaqua, who may
be sent anywhere in the world at their master's command.
Ithaqua has been worshiped worldwide, with scholars drawing parallels
between the Great Old One and the gods Quetzalcoatl, Thor, and Enlil. In
the north where his true nature is known, Ithaqua is more widely feared than
worshiped, and most of his cults died out in the early 19th century. Centers of
this cult existed in the town of Stillwater, Manitoba, the inhabitants of which
all vanished in the space of one night, and Cold Harbor, Alaska. In all instances,
these cults involved human sacrifice and kidnapping of those opposed to their
worship.
The Wind-Walker is also responsible for a series of disappearances in
Canada and the North. In most of these cases, a person vanishes and nothing
is heard of them for months or even years. Later they are found encased in
a shroud of downy snow with evidence of having fallen from a considerable
height. Such victims may also be alive, babbling of the glories of Ithaqua, and
have in some cases carried strange items that have plainly originated in widely-
removed parts of the world. Those who have been in close physical proximity
with the Wind-Walker are often able to endure the coldest temperatures without
discomfort, or even transform into a creature physically resembling Ithaqua.

None survive long after their return.
Some say that Ithaqua serves the Great Old One Hastur, but there seems
to be little hard evidence to support this.
Ithaqua is probably one of a race of similar beings, as at least one encounter
between Ithaqua and another wendigo has been repo rted. If this is true, Ithaqua
is still the only wendigo to visit Earth regularly.
