Celestial

The Celestials were a immensely advance ancient race of sentient magical forces, and the first beings to ever exist in the Multiverse, and are the progenitors of all forms of Magic. Once serving the First Firmament, the very first universe in the Multiverse, the Celestials went against the Astrals, which then began the Celestial War, to which became the strands of the timelines in the Multiverse.

A scarce few know of their exist in the Seventh Cosmos, but only known one is Starswirl.

Origin
In the beginning of the Multiverse, the First Firmament was perfect, but suffered from loneliness, and so, created the Celestials, and progenitors of all magic in the distant multiversal future.

Many of the Celestials went, and created entire galaxies, and solar systems and life on it, in hopes to impress the First Firmament, and try to bring it happiness, and not let it be lonely. However, the Celestials wanted their planets, and all things they made to evolve, to which was a sacrilege, and goes against the First Firmament. A such, the First Firmament made another sentient race of forces known as the Astrals, to which the First Firmament ordered the Astrals to fight against the Celestials.

Celestial War
The Celestial War is fought between the First Firmament and the Astrals against the "rebellious" Celestials. Throughout the first universe, both side diminished each other in quick succession, to the point that the Celestial known as Aion shattered the First Firmament, causing ruptures of other realities to split off. What remains of the First Firmament, and the Astral fled, and soon the universe forms a collective sentient entity, the Second Cosmos, to began the first Multiverse.

Second Cosmos
The Second Cosmos or the First Multiverse began, and the Celestials then created their own servitors known as the Æsir to fight against the First Firmament and the Astrals. They did this throughout the Multiverse Renewl.

Harmony & Eris
When the Seventh Cosmos entered into existence after the Sixth Cosmos, the Celestials are confronted by Harmony and Eris, the two cosmic forces of order and discord. Harmony and Eris told the Celestials they wish to offer something, in return they do what they ask. Harmony and Eris wanted a reality that is split into two dimensions so they made create without bugging the other.

The Celestials agreed, and made two dimensions, and Harmony and Eris allows them to enter, and leave and do what they wish within these dimensions, which greatly pleased the Celestials.

Human World
After Eris created her realm, planet and a race known as Humans, the Celestials then interjected by placing many other sentient creatures onto the planet, causing the human, and all life to evolved over its existence. Due to what the Celestials had done, Eris is very happy as her planet is now truly a disharmony land, which war, chaos and strike and mistrust and mistreatment.

Pony World
Harmony on the other hand, created a realm of everlasting peace, kindness and land of wonder. However, one of the Celestials, Cronus, betrayed his fellow brethren, and started to crated other life on the planet Harmony had made. To confront the Celestial invader, Harmony made the Elements of Harmony, two alicorns which used the power of the 12 gems against Cronus, and with the help of the Celestials, created Tartarus where the two Alicorns banished Cronus to.

Eight Cosmos
In the Eight Cosmos, the Celestials had vanished after the Seventh Cosmos was destroyed. However, the Celestials had left be hide many very very ancient relics and artifact, from objects going back to even the First Firmament, the very first universe to ever exist.

Armor
The Celestial Armor is the physical manifestation of their physiology, and can only be manifested once. These armors allows the Celestial to inhabit the 3rd-dimensional realm, and interact with the physical matter, and perform activities, and conjure their magic forces to alter all things around them, and handle their technology.If a Celestial has their armor destroyed, they are classified as "deceased" as there is nothing to contain their essence, as they are a force in the Multiverse spreading across the universe. According to the remaining Astrals, this is how Magic began to spread across the Multiverse.
