Nihl Kaguya

Nihl Kaguya (, Niru Kāguyā; lit. "Imperial State Magic: Territorial Change") is a forbidden Holder Magic and considered to be one of the most powerful forms of magic that's been artificially created. Alternatively called the "Anti-Dragon Vein Magic" (反竜脈の魔法, Hanryūmyaku no Mahō), it's seen as something that "violates" the laws of magic to one's benefit — only at the cost of other's untimely destruction.

It's been used by various governments all over Earthland, being very prominent during times of war. The constant use of its has brought about an untimely end to many civilizations, thus was banned by the Magic Council and all information pertaining to it confiscated and buried within their archives. Currently, a select few still use the magic for the benefit of their countries — thus deemed as international criminals in the eyes of the Council.

Trivia

 * This magic is wholly based on the State Territorial Magic seen in the anime series, Chaos Dragon: Sekiryū Sen'eki; it's slightly modified for the author's personal use in his stories.
