Soul Extinction

Effect

This High Art Spell utterly excises a soul via spreading its essence across the entirety of the multiverse. Beyond recall of even the gods. Whomever it was is gone and their memory fades from existence.

Side/Secondary Effects

The subject is subjected to a disintegrate effect, The caster is irrevocably marked in such a manner that the denizens of the underworld inherently hate the caster for daring to remove a single being from the cycle of life and death.

Manifestation

The effect itself is unseen but its passage is unmistakable. The ground cracks from the sheer pressure of this malignant magic. Causing significant structural damage as a byproduct. Small debris floats upward of their own volition. The very air parts creating a momentary space devoid of air.

Source

It is unknown who first created this sacrilegious bit of High Art. Some suggest The Lich King is its creator but his well known trade agreements with beings of the underworld seems to outright contradict this. The gods in general highly condemn this spell and the gods of the afterlife are known to place bounties to outright order any known user to be assassinated with extreme prejudice.
