Laplace's Demon

**Laplace's Demon** was a notable published articulation of causal determinism on a scientific basis by Pierre-Simon Laplace in 1814, a theoretically figure that knows everything.

## Appearance

Laplace's Demon is a goat like figure. He has a body of a human but the head of a black goat with yellow fire on his head, between the horns. He has goat legs but black human arm. He has black skin with fur.

Laplace's Demon wears black suit with red tie and black coat outside.

## Personality

Laplace's Demon described himself as having no personality. He stated that himself as a mere theoretical figure. He has no interest in the world itself but he deligated his life to protect harm to the planet.

Due to his name's theory statement, Laplace's Demon believes that everything was determined beforehand. Thus, he himself has no free will and only acts as an actor within this grand movie theatre.

However, his view on fate changed during the Fall of Mankind, the Coalition used Third Magic to banish him from the world. At this point, he realized that True Magic was outside his prediction, outside destiny. A flash of enlightenment crossed through his head. Unfortunately, he could never experienced his new idea of life because he would be killed at that point by Koken Chocolate Gentoshi.

## Background

Laplace's Demon refers to the theory of Pierre-Simon Laplace in 1814. According to determinism, if someone (the demon) knows the precise location and momentum of every atom in the universe, their past and future values for any given time are entailed; they can be calculated from the laws of classical mechanics. This idea states that “free will” is merely an illusion, and that every action previously taken, currently being taken, or that will take place was destined to happen from the instant of the big bang. Discoveries and theories in the decades following such as irreversible processes in thermodynamics suggest that causal determinism is wrong or incompatible with our universe.

As the personification of that theory, Laplace's Demon dedicated his life to do nothing and only acted when harm was caused to the planet.

He participated in the Fall of Witches as he believed The Ancestral Witches tried to harm the planet but did nothing except giving prophesized advice to Meridiana and Koken Chocolate Gentoshi.

During the Fall of Mankind, the Coalition condemned him for destroying humanity and destroyed his body, ensuring him not to enter the planet by banishing him using the Third Magic.

## Abilities

As a Transcendent of the Bridge Builders Cabal, Laplace's Demon is said to be powerful enough to rival the regular magic side on his own.

### Formless Personification

Laplace's Demon is the personification of the theory by his name. Thus, he is not a living being per se and cannot be killed by destroying his body. Only banishing his soul by True Magic can "kill" him. Laplace's Demon is noted to be nigh-invincible because of this.

### Laplace's Demon

The power of the theory and his name. Laplace's Demon perceives time in a non-linear fashion. This means that he sees the past, present, and the future simultaneously. Likewise, he can grant others with this "atemporal" vision. This ability granted Laplace's Demon the vision to know all atoms and can predict, view everything. However, things like Miracles and True Magic can still exceed himself.

## Trivia

Despite being referred as "he", it should be noted that Laplace's Demon is the personification of a theory so he doesn't fall into any biological category. He isn't even a "demon" by definition.
