Annuli Hermagedon

Annuli Hermagedon (, Anururi Erumagedon; Latin for "Apocalypse Ring", Japanese for "Destructive Circle: Immense Authority of Heaven and Earth") is considered to be one of the most destructive Magic Phenomenon known in existence, the sheer power it exudes acclaimed to equate a natural disaster of epic proportions. It's later revealed to be something man-made — formed from the residual energies exerted from two combatants of equal strength. It's because of this that the event is alternatively referred to as the "Tenpenchii Magic Scale" (天変地異魔法計量器, Tenpenchii Mahō Keiryōki); the greater the ring, the more potent the disaster in-question.

Overview
"When two powerful beings of equal stature clash, the combination of their exerted power are able to shift the very fabrics of their surroundings. The greater the power, the more apparent the effects become."

Trivia

 * This is more or less based on the Emperor Ring from the anime/manga series, Toriko. The author chose to create this article to measure the combatants' power levels whenever they battle in the storyline; this essentially separates the strong from the average and the weak.
