Fimbulvinter

Fimbulvinter (, Finburubinteru; lit. "Frozen Deities, Apocalyptic Subzero Desolation") is an exceedingly dangerous form of Elemental Magic used by the Spriggan, Galiaene Brizo — inherited from her now-deceased clansmen, serving as absolute proof of them being the most powerful cryokinetic users in all of Earthland. It also serves as the reason for her title as "Vicious Incarnation of General Winter" (冬将軍の湿権, Fuyushogun no Shimeken) amongst the group, labelling her as the most powerful cryokinetic user to-date.

It's a form of Caster Magic and a form of Subspecies Magic — the magic's very name alluding to the element of ice; interestingly enough, Galiaene identifies this as a form of Enchantment as well, due to its mechanics, and an Ancient Spell, being older than most magics in the modern era — predating even most forms of Lost Magic. It's alternatively referred to as the Permafrost Deathly Domain Magic (永久凍土々気領魔法, Eikyūtōdo Tokeryō Mahō), by Galiaene and a myriad of her victims because of damage inflicted and its incredulous extensive radius, making it nearly godlike.

Trivia

 * This magic is wholly based on the 40,000-Year Ice Jade Emperor Scorpion from the manhua, Douluo Dalu II — Jueshui Tangmen, one of the author's favorite comics in general.
 * This magic was created out of the desire to have each member of the author's interpreted Spriggan Twelve group to have their unique magic or ability, making them more powerful than the standard mage in the storyline.
 * It should be noted that Galiaene was the only person in the group that was slated to have a plain magic taken to extremes; in a sense, this magic can be seen as such, as its a much more powerful variation of the typical Ice Magic she utilizes.


 * The author confirms that this magic is the most powerful cryokinetic-based magic seen in the Heroic Chronicles as a whole, surpassing even the likes of Dragon Magic and Slayer Magic in terms of power and versatility — matched only by "godly powers"; this is to further emphasize the power of its user, and by extension — the fanonized group she belongs to.
