Chaos Magic

> *"Magic not of this realm. I will not get into details about Chaos Magic. I am sorry, but I resolutely refuse. Suffice to say that magic is a force that lives all around us, and that force is what we draw upon for spells, wards, rituals and the like. Chaos Magic differs because the magic is fundamentally different. It is being drawn from a different source altogether and the force does not act in the same way. It is magic borne of chaos and impossibilities. It is, in many ways, how the magic we know of today came to be."*

— Emily Riddle revealing the existence of Chaos Magic to Harry Potter via the linked diary in the aftermath of the Duelling Club, Harry Potter and the Sacrificial Slytherin: Chapter 21: Dangerous Duels and Deadly Drama Part III, December 17th, 1992.

Chaos Magic as a branch of magic has been buried by those who control the world. By those in the known it is deem dangerous on a whole different level compared to anything else. Chaos Magic is not meant to be warped and controlled, and when that became a possibility, it was an apocalyptic problem.

In the British Isles one would disappear in the middle of the night for simply knowing about this ancient and forgotten branch of magic. Any mention of it has as well been wiped out of the Isles centuries ago.

There are most ancient places in the world where information about Chaos Magic can still be found. These places are were magic as it is currently known has been born — where chaos was first controlled.

## Incantations / Magical Phenomenon:

**Priori Incantatem:** It takes place when two magical duel with wands containing brother cores. A battle of wills ensues that forces the beads of light connecting their two wands to make contact with one of the wands. This triggers the loser's wand to regurgitate the spells it has most recently cast. Overall, the victor gains an eternal advantage over the opponent that fell to their will.

> *In many ways, Priori Incantatem happens because of an impossibility. Brother cores are intrinsically linked to one another. By their nature, they are meant to work in harmony with one another, and will optimally perform when that scenario is the reality. They are extremely reluctant to fight one another, so they seek to end the conflict in the most decisive yet least destructive way possible. By forcing the battle of wills upon the two combatants, it is magic’s way of seeking resolution. To magic, the victor of the battle is the one most worthy to wield said cores, hence, they will now have an eternal advantage over their adversary.*

**Fiendfyre:** The spell has rather strict esoteric requirements that cannot be met by the average magical. Even those that meet said requirements oftentimes are incapable of casting it as they lack either the power of the control necessary to not kill themselves with it.

One who wishes to successfully cast Fiendfyre needs to hate a person so badly that they are willing to destroy themselves if it meant destroying the person in question.

> *It is as I suspected and feared. I will not speak the name of that spell, even if you heard it cast aloud. It is an evil far beyond Priori Incantatem because it is one of the instances I spoke of earlier that caused the branch of magic to be buried deep within the belly of history. It is a wizard controlling this branch of magic to do things that should not be possible within this world. Albus Dumbledore is quite probably the only person alive who could cast that spell and not disappear in the middle of the night for committing said action. He is also one of probably only three people in the world who knows how to cast that spell.*

**Hölleneis:** Can be used as a counter spell for **Fiendfyre**. It creates something akin to a black smoke or fog, but a thousand times more terrifying, giving off a similar feeling to the use of Fiendfyre — but somehow the exact opposite. The air around the spells seems to an external observer as growing heavy and hard to take in, like all the oxygen around it has been instantaneously frozen solid.

## Creatures:

The Basilisk, also known as the king of serpents, is created with the aid of Chaos Magic. The ritual to create of is difficult to speculate on, even for people well versed in this branch of magic, such as Gellert Grindelwald. Normally, a basilisk's gaze would kill the victim, but, it is possible, to modify one in such a way — maybe via either Chaos Magic, Hemomancy, or a combination — such that their gaze would petrify their victims instead.
