Brotherhood of the Kraken
Alignment: Neutral Evil
Symbol: A black 8 finged hand
Portfolio: Evil, Water, Destruction, Madness, Magic
Background: The largest of all Cults of the Dragon Below with the possible exception of those that revere Nyarlathotep, due to his association with The Traveller, it is certainly the most well organized and influential. The Brotherhood of the Kraken is so influential that some scholars have begun speculating that it is the origin of all worship of the Devourer as a Sea God rather than the other way around.
The majority of Cthulhu's worshippers don't actually know him by that name as it is recorded only on a very few select priesthood's tablets. Only the Necronomicron as found by one insane Lhazaar wazir lists him by name. Thus, only scholars of Morgrave University and the Arcane Congress have knowledge of his name outside of the cults highest echelons.
They instead refer to him as "The Great One", "The Sleeping Beast", "The Great Serpent", "Demogorgon", and "Asmodeus." That the two later two characters have been created from myths about him is indication of how debased Dragon Below theology can become. In many religions, the Devourer and Cthulhu are worshiped as one in the same. These cults have little to do with the main one but are reacting to the increase in their gods power.
The majority of the society's followers are sea-dwelling creatures of Eberron. The Kuo-Tu, Sahuagin, Merrow, Scrags, and other sea born monster races that treat him as an aspect of the Devourer. Those cultists that revere him along Xen'drik tend to intermarry with these races and produce rather degenerate half-breed offspring. Lord Shadowspawn has enlisted countless races to his service with the aid of the Demon Wars monstrosity Dagon (CE M Dragon Turtle/Kraken Abberation-Hybrid Priest of Cthulhu 3) that most assume is the god himself. A similar being called Mother Hydra exists but it has not chosen to yet reveal itself.
Being an extra-dimensional evil, Cthulhu does not actually sleep anywhere yet Dagon has transformed the city of R'leyh into a focus for the monstrous beings power. The city will rise from the depths of the oceans that the Dragons sank it to when the spells are suitably completed with the alignment of the stars. Lord Shadowspawn himself can't complete the Epic Level magic necessary but the aid of countless willing magicians to Commune with him has given him the power to make a go of it. It is a complex series of rituals that will take months even as the city is immune to even Draconic attempts to find it.
The land dwelling faction of the cult includes the Abyss Walkers Orc Tribes that are a large and powerful organization that has ties to the Emerald Claw. Erandis D'Vol long discovered that Cthulhu had a substantial following amongst evil magicians due to the fact that evil rituals to him were often rewarded with increases in power or gaining in 'enlightenment.'
Despite her best efforts to stamp out this heresy in her cult, almost the entire Brelish faction of the Emerald Claw defected at the possibility of world domination offered by him. Most are Karrnath military themed and very fascist in nature despite their multiple ethnicity.
The cult's wide following means that almost anyone could actually be a part of it and its members have begun rapidly agitating the existing chaos in hopes of being able to spare themselves the resultant destruction that is likely to occur to the world. They are destined to be disappointed.
Dogma: The rising of The Great One will result in the destruction of all the world's civilization. This is inevitable and to be encouraged for it will bring about the Master's swifter return. Upon the arising of the Master, those few who venerate him will be spared with a select few elevated to the status of the Great Old Ones (droles on about the rewards that will be reaped by the chosen few, blah blah). Sacrifices are usually sentient life in nature while water and sex plays an absurdly prominent role in the religion.
Cthulhu: A CE Greater God by the standards of D&D, Cthulhu is the most powerful of Khyber's spawn and one of the few genuine deities on Eberron. Because it is a Spawn of Khyber, it is indestructible by human hands and only the power of the Progenitor Dragons has the ability to bind it anew. Any attempt to actually destroy the monster would be a hopeless exercise in futility. The only way to genuinely oppose Cthulhu is to prevent his awakening as even its avatar would be able to decimate the world.
