Korvaddegon is classified as a Lesser Idol, and is capable of granting powers as a patron to witches and warlocks, and perhaps clerics and the like who venerate the Dragon of Calamity, bringer of the Stagnation Plague. Consult your GM if you are interested in following or recieving power from Korvaddegon the Calamity as described here.
Spend an hour in silent prayer to Korvaddegon surrounded by draconic scales, or symbols or draconic power in some way. When your hour of prayer is done, smash a small to medium sized rock or boulder.
All weapons you wield are infused with the Anarchic special weapon quality. You may, once every 2d6 rounds, emit a boulder from your mouth and target a creature with a ranged touch attack, hitting them as per the Rock Throwing Universal Monster Rule(Doing 4d6 Magic Bludgeoning Damage Default) that acts as a splash weapon, dealing minimum damage to all adjacent squares.
Little remains of the myth of Korvaddegon, unfortunately - thanks to the actions of The Wanderer
which completely laid waste to the civilization that was believed to have been dedicated to housing it far in the northern tundra, there now exists only the barest scraps of information about the legendary Dragon of Calamity. From what is known, it was an engine of unparalleled destruction that terrorized the northern wastes of Zheng-Kitar for centuries and possibly even Milennia - the few records that remain speak of it breaking free from its original prison and spreading something written of only as "The Stagnation Plague" to the civilization that once inhabited the far north of the tundra, spreading a disease of the spirit with every attack that stole the ability for change and adaptation from the souls of those it attacks, creating strange, stagnant creatures who could never again have original ideas, embrace change, or move on.
It is unclear how it was imprisoned for a second time, but it is assumed to have been in some form or fashion by the ancient civilization that has been recorded as having existed long ago, far in the north of the Shenchuan Tundra - even the name for this civilization has been all but lost. Now, in the modern day, most of the myths of Korvaddegon have been recovered by those brave explorers who have braved the lands walked by The Wanderer
, risking death and destruction to recover scraps from the ruins of the lost cities of this ancient civilization that remain unflattened by The Wanderer
There is evidence to support the existance of the legendary dragon known as Korvaddegon the Calamity in the ruins of the aptly named "Northern Civilization" that lays in ruins in furthest reaches of the Shenchuan Tundra, where lone brave explorers who have braved the(Literal) stomping grounds of The Wanderer
have found in those cities great Bas Reliefs carved onto the walls of crumbling ruins depicting a gigantic dragon or, in some cases, a dragon-shaped mountain, assaulting a terrorized people infecting them with some terrible disease.
Adding on to this evidence is a series of Stone Tablets recovered from the only successful expedition to any of the standing ruins to this "Northern Civilization" - these "Dyzak Tablets" are things of legend which, while serving as one of the major sources of information from the Age of Rebirth, also contained records of the time after, where in the waning years of the Northern Civilization it was beset by a terrible draconic beast that had escaped a prison the people there had known of. So, while little is known of the actual dragon itself beyond its terrifying status and its deadly "Stagnation Plague" that it seemed to bring, it is believed to exist...imprisoned once again somewhere out in the world, waiting to be release...
The myth of Korvaddegon is only known to especiously studious scholars who study up on The Six Husks, or those rare few who make a habit of studying the fabled "Northern Civilization".
While not confirmed, it is also thought to be a cultural boogeyman of the Yatsimoan
people, who speak of it as a being known as "The Great Si'yahna" - a figure that they speak of as being diametrically opposed to civilization and progress, which brings a deadly mental affliction that results in entire peoples staying stuck in the past, unable to learn or accept new ideas or things and staying as they were forever. While not confirmed, this "Great Si'yahna" is believed to be a myth about Korvaddegon's actions or ancient history that was twisted or, perhaps, alluding to the great beast itself. The islander and Kitsune
clans there have little desire to speak about it - especially the Kitsune
, who consider speaking the name of the beast a bad omen.
The only culture it remains persistent in in the modern day is the Yatsimoan
people, who consider it a boogeyman and bringing of calamity - an agent of opposing advancement and civilization that, if freed, would damn the world to stagnation for eternity - never advancing, never changing, never becoming different.
It is only mentioned in the most ancient of Literature in the ancient "Northern Civilization" - it is only spoken of in the Yatsimoan
people's culture, as they do not often pass down information outside of the spoken word.
The only remaining art that exists of the legendary Korvaddegon are the Bas-Reliefs in the remaining ruins of the "Northern Civilization" and the depictions of it on the "Dyzak Tablets" recovered from the same locations.
