Zombie Magic

Zombie Magic (不死生物の禁魔法 (ゾンビの魔法), Zonbi no Mahō; lit. "Forbidden Magic of the Undead Creature") is considered to be one of the most grotesque forms of the Black Arts — utterly violating the principles of life & death for one's own gain. It's also one of the few magics that gives the user a form of immortality — turning them into the very creature that they control.

It's said that this magic was used to overthrow many government in ages past, causing much destruction and mayhem. It also caused the deaths of over thousands upon thousands of individuals, most of whom were mages. This caused it to gain the moniker, "Potent Magic of Bio-Terrorism" (命震駭行為の強い魔法, Meishingaikōi no Tsuyoi Mahō) — denoting to the danger it causes to the world as a whole. Knowledge of it was lost when its creator was captured and sealed away by past government officials. However, as a fail-safe, he recorded the magic in various tomes & texts, sealing them in various parts of the world so that it may thrive in the late future.

Known to be one of the oldest forms of its kind, it's uses the principles of both Living Magic & Necromancy to properly function; this classifies the art as a form of Subspecies Magic. It's also similar to most forms of Subordination Magic, albeit with slight differences. It's considered to be an extremely versatile Caster Magic, as it gives the user various advantages. It's considered to be one of the few Black Arts forms that's able to utilize Magical Barrier Particles to an extent. This makes it highly dangerous in the hands of any mage, especially one well-versed in the Black Arts.

Overview
"A magic that gave the wielder to create & manipulate vast armies at will. It enslaved the minds of its victims, bending and twisting it to their liking. It violated the very principles that shouldn't have been touched upon. It even gave its wielder to manipulate the very substance that's known to be a bane to mages worldwide. However, the true terror found in it is its ability to make the user "immortal" — becoming the very thing they turn others into. Truly, it's a magic that should have never existed..."
