Kostchtchie
Kostchtchie is known as the Prince of Wrath, a demon lord and a patron of frost giants and rage.
Description
Kostchtchie was a 24‑foot (7.3‑meter) tall muscular brute with hunched shoulders and stubby, bowed legs. His head was malformed and his face was flat, ugly, and hairless except for his eyebrows. His skin was a sickly yellow. He always carried with him a massive hammer.Personality
Kostchtchie is a hateful, imperious, and violent dullard who revels in the frenzy of combat. He is desperate for power and validation, but fearful in the face of powers greater than him. Befitting his title as the \"Prince of Wrath,\" Kostchtchie is renowned for his rages. However, he is petulant and childlike in many respects, and these rages often resemble demonic tantrums. He is known to be easily amused, and sometimes even spares lesser beings if he finds them humorous. Kostchtchie is particularly attached to his massive enchanted warhammer, known as Matalotok.Kostchtchie is ambitious, but prone to idiotic fixations which distract him from his larger goals. For example, despite knowing that his realm, the Iron Wastes, is an infinite plane, he is still obsessed with trying to conquer all of it.
He is extremely misogynistic. He has decreed that frost giant females of tribes under his control are to be fed to his warriors when they become too old to bear children.
Activities
Kostchtchie is a relative newcomer among the notable demon lords, and is considered something of an upstart. He rules the Iron Wastes, the cold and icy 23rd layer of the Abyss, and has ambitions of conquering other layers as well. His primary goal is to rule over all frost giants as their god. He is known to lead raids in both the Prime Material plane and Jotunheim to \"liberate\" frost giants from their gods, demanding they bow to him or be exterminated. He dismisses any frost giants who refuse to bow to him as not \"true giants.\" Supposedly, the knowledge that there are frost giants who do not accept him, or who reject his worship outright, is a constant source of anguish for Kostchtchie.He is known to train some murderous frost giants in the art of wizardry.
Kostchtchie frequently wages war on other layers of the Abyss, and holds a strong hatred of other demons. He is known to harbor ambitions of wiping out the entirety of the tanar'ri from existence, and has made great progress toward the extinction of the mavawhan, the ice demons who had been the original rulers of the Iron Wastes before he assumed control.
Worshippers
Kostchtchie was worshiped by frost giants who had turned away from Thrym, which included many who sought power through learning arcane magic, called his frost mages. Prior to figuring out how to grant cleric spells, his "priests" were wizard cultists called wyrmkin, feared for their ability to summon white dragons. Subsequently, he managed to grant his followers access to the chaos, evil, fury, war, and winter domains. Many high ranking members of the clans and cults that swore allegiance to Kostchtchie undertook efforts to purge themselves of all emotions except wrath, becoming known as a thrall of Kostchtchie.The most important tenet of Kostchtchie worship was conquest, with his followers tasked with expanding his influence and forcibly converting frost giant clans. A large number of his faithful were members of clans which had been conquered by Kostchtchie or his followers, or who had been abducted by these followers. Frost giants could also invoke him with bloody sacrifices made upon alters of ice with hopes of summoning his aspect. Those followers of his who distinguished themselves in battle were invited to join his massive horde of warriors in the Iron Wastes.
No worship of any deities or powers other than Kostchtchie were permitted in the clans that swore allegiance to the Prince of Wrath, and any "heretics" were dealt with brutally, especially if the heretic was female. Only males were permitted to hold any power within his cult, and often the cult sought to eliminate women from their numbers altogether. If a clan of Kostchtchie worshipers could reasonably sustain its numbers by abducting young males from other tribes, they preferred to sacrifice their females.
Aside from frost giants, Kostchtchie had some scattered cultists among humanoid and ogre barbarian tribes, mostly in colder climates. Some tanar'ri priests were known to pledge themselves to Kostchtchie's service. While Kostchtchie considered these his lesser followers, he believed that they nevertheless had their uses.
Relationships
By establishing himself as a deity of frost giants, Kostchtchie directly encroached upon the domain of Thrym, though that titan did not take direct action against the demon lord. The dwarven deity Clangeddin Silverbeard considered Kostchtchie, as well as the other evil giant deities, a hated enemy.Kostchtchie's hatred (and perhaps fear) of women was legendary, and was at least partly driven by his relative powerlessness in the face of certain important women in his life. He was indebted to both Baba Yaga and Iggwilv (a.k.a., Tasha), for giving him immortality and his hammer respectively, and the former was known to have continued manipulating him long into his reign as a demon lord. He also had a history of animosity toward the celestial paragon Gwynharwyf, so much so that he liked for sacrifices made in his name to be done so in her likeness.
He tended to consider most other demons of the Abyss to be his enemies, and had no allies among the other demon lords. He especially hated the demon prince Graz'zt, who had humiliated him in the past, and in his quest for revenge he had begun making overtures of an alliance to Obox-ob.
Kostchtchie was frequently accompanied by his "hounds," a pair of leucrotta that were three times larger than normal. He was very attached to his giant white dragon mount of ancient age, named Svafnir. He was also served by the rageborn, ferocious demons that appeared only upon his own arrival in the Abyss.
History
Kostchtchie's origins are somewhat shrouded in mystery, largely because of his claim to be a frost giant deity. His preferred story is that he was once a king among frost giants before his apotheosis, but this was an obfuscation meant to legitimize his claim to rule over the giants. Even as a demon lord, he was known to identify as a frost giant, and to became enraged and violent at anyone who suggested he was not.Kostchtchie was born as a mortal human man, but one who was severely deformed. Spurned by tribes and by women, he was driven to anger and rage. He turned to brutal murder, slaying every woman who ever mocked him and crushing the skull of his former tribe's chieftain with his bare hands.
In time, he was found and mentored by the great witch Baba Yaga. She gave him a set of cursed, nested skulls. Inside the innermost skull—that of a tiny quasit—was hidden a black diamond, and Kostchtchie used dark magic to transfer his soul into this gem, granting himself immortality.
Now unable to be killed, Kostchtchie's body grew both larger and more hideous, until he was the size of a great giant. His tribe grew to the size of a kingdom, and their murderous exploits became infamous and were noticed by powers from other planes of existence. The celestial paragon Gwynharwyf led an army against his forces, but she was not able to overcome him until she discovered the demonic source of his power. She found and destroyed the skull and its gem, returning his soul to his body so that she could slay him, sending his hateful soul to the Abyss. However, this was only a minor setback for Kostchtchie, whose body was recreated in the Abyss in demonic form.
At some point, the witch Tasha bestowed Kostchtchie with the hammer Matalatok, which had been originally crafted by Thrym, god of frost giants. Kostchtchie used it to dominate a clan of frost giants and would ultimately declare himself a god to them. Kostchtchie led his clan aboard a flying vehicle known as the Ark of Kwalish to plunder treasures from across the planes, including a brutal raid on the City of Brass. The clan was scattered and Kostchtchie banished back to the Abyss during a raid on Scalding Mountain, after which he turned his attention to gaining power within the Abyss.
Kostchtchie first claimed the Iron Wastes by driving the native mavawhan out of the plane's core. His invasion caused raging storms to sweep through the layer, from which emerged the first rageborn demons. Kostchtchie then proceeded to wage war on other minor demon lords from across the Abyss, slaying at least three. He also antagonized Thrym, doing things such as capturing and imprisoning his brother, Grjotgard. It was unclear whether his actions against the forces of the Abyss and Thrym were out of his own ambitions of conquest, or if Tasha was pulling his strings.
During this time, Kostchtchie became an unwitting pawn in the endless feud between the Dark Prince Graz'zt and the Queen of the Succubi Malcanthet. Graz'zt infiltrated Kostchtchie's citadel disguised as Malcanthet and seduced the Prince of Wrath, seeking to ultimately pit him against the succubus. Kostchtchie became ashamed and inconsolably furious when the ruse was revealed to him, and proceeded to wreak havoc across half of his own realm before launching a fruitless invasion of Graz'zt's domain of Azzagrat
Around the Year of the Stone Giant, −160 DR, Kostchtchie's hortha was summoned by a cabal from Narfell to assist them in their war against Raumathar, a conflict which would become known as the Great Conflagration. Frost giants gathered under this hortha from the Icerim Mountains and fought on Narfell's side, ultimately conquering Winterkeep and coming into conflict with an avatar of Kossuth.[note 2]
At some point in the mid-to-late 14th century DR, Kostchtchie sent an aspect of himself to the eastern reaches of the Spine of the World mountains to conquer humanoid and giant settlements and to subjugate local frost giants. This aspect completely obliterated at least one small town in the Lands Against the Wall, and came to the attention of a group of adventurers out of Silverymoon.
Later on, Kostchtchie participated in the Blood War by leading an attack into Avernus. In a battle on the shores of the River Styx, he crushed the Nine Hells' 8th Infantry Legion, but was defeated in combat by the archdevil Zariel. His hammer, the mighty Matalotok, was taken by Zariel for her own use, and he was imprisoned in an Avernian ravine which came to be dubbed "Kostchtchie's Maw." From his prison, his howls of rage and demands for release could be heard for miles.
Some time after the Year of Three Ships Sailing, 1492 DR, Kostchtchie was freed from his infernal prison on Avernus. His prison was repurposed to hold captive the soul of a powerful giant king.
