Heaven

"There isn't one Heaven, each soul generates its own paradise."

- Castiel Heaven, also called The Attic, The Penthouse, or even Upstairs, is an ageless, ethereal, holy realm created by God, intended to be the home-realm of both himself and his angels. It serves as a dwelling place and a base of operations for all angels, and is a final resting place of worthy human souls.

Overview
In its history, Heaven has had two civil wars. The first was when Lucifer became jealous and angry of the creation of mankind and, subsequently, led a rebellion against God. The second was between Castiel and Raphael after the aversion the Apocalypse. Raphael had wanted to restart it by freeing Michael and Lucifer while Castiel fought to prevent it. God resided in Heaven with his angels until his departure sometime in the distant past. In God's absence, the archangel Michael led the angelic Host and directed the affairs of Heaven. Raphael was also an authority.

The appearance of angels in Heaven is not necessarily human, though they usually stay in their vessel, as it isn't always easy to find a suitable vessel for angels. For example, Zachariah says that in Heaven, he has six wings and four faces. Angels draw some of their powers - demonic exorcism, healing, time travel, and resurrection - from Heaven. Those who fall and are "cut-off" from Heaven are weakened and are not allowed to return on their own the only exception to this is Archangels. Seraphs have also demonstrated the ability to hold onto all of their powers when cut off. It is still possible for the banished to communicate with Heaven. Anna can hear other angels speaking, even without her grace. Castiel is able to communicate with Sam and Dean Winchester through a link to electronic equipment - such as a radio or TV - in their memories.

Heaven also serves as a destination for deserving human souls after death. They occupy the happy memories they experienced on Earth, reliving them in their personal Heavens. It is unknown how a human soul is allowed salvation in Heaven. Joshua suggests that it is on a case-by-case basis and can be God's decision; this is the case with Sam and Dean. Raphael says that if a person is devout enough, it can trump all sins (which is why the disgraced Enron executive Ken Lay got into Heaven).

Conception and Early History
God created Heaven as a realm to house himself and his angels. This realm also served as a final resting place of souls deemed worthy.

The center of Heaven is called The Garden (Zachariah refers to it as "Mission Control"), and, like the rest of the realms, each person sees it how they want to. The Garden can be reached by the Axis Mundi, which is often seen as a river or a road, depending on the person.

Most demons fear Heaven's inhabitants, God and his angels, and will flee from them on sight. Some of the more powerful demons like Alastair, can send angels back to Heaven, but only someone with an angel or archangel's sword, God, or Death, can kill an angel. Despite the fact that Uriel states that only an angel can kill another angel, Zachariah is killed with an Angel sword or dagger used by Dean.

The Apocalypse
According to Joshua, God is walking the Earth and is not interested in helping the Winchesters stop the Apocalypse. Since God's abandonment of Heaven, Michael is assumed to have taken command as his right as "Viceroy of Heaven" with some assistance from his younger brother, Raphael.

Civil War and Proclamation of the New God
After Michael was trapped in Lucifer's Cage, Raphael took over, leading it like a dictatorship. When he announced his plans to free Michael and Lucifer and restart the Apocalypse, Castiel opposed him. This resulted in a civil war between Raphael's forces and Castiel's followers. The war ended when Castiel absorbed all the souls of Purgatory and destroyed Raphael and his followers. He then declared himself God and took control of Heaven. However, he then disappeared and was presumed dead, and Heaven once again fell into disarray.

In the aftermath of Castiel's disappearance, Hester, who was once part of Castiel's garrison, took command of the remaining Angels. She was assisted by Inias, also an Angel from Castiel's garrison. In the wake of Hester's death in Reading Is Fundamental, it is unclear who is now leading Heaven. It is possible that Inias is now in charge, as he is seen commanding the Angels to take the Prophet Kevin back home at the end of the episode.

Factionalized Heaven
It's revealed by Metatron that Heaven is currently at war, with multiple factions of angels fighting for supremacy, as without the Archangels and following Castiel's decimation of Raphael's followers there is no clear leader. Naomi is simply the leader of one such factions. Hence, Metatron initiates the plan to close Heaven off until things cool down and also so that the in-fighting doesn't spill onto Earth.

However, Naomi later reveals to Castiel, and Metatron later confirms, that his intent was not to seal Heaven, but to cast all angels out of it. Taking the ingredients Castiel had acquired (the nephilim's death and the cupid arrow) and Castiel's grace, Metatron casts a spell that causes all angels to permanently fall from Heaven.

Hierarchy
The armies of Heaven are divided into several classes for different purposes. Warrior angels who served as foot soldiers were grouped in garrisons charged with specific tasks. Castiel's garrison, for example, was assigned to watch and protect the Earth. Each garrison is led by a Captain. Garrison Captains report to Seraphs, such as Zachariah, who in turn answer to the archangels themselves. In God's absence, the archangels are the highest order of authority in Heaven.

Garrisons can, to some extent, be compared with military special ops units. The lowest angels on the celestial chain are equivalent to Privates and Corporals. More powerful angels have ranks comparable to Sergeant, while a specialist like Uriel could be described as a Master Sergeant, aiding the lieutenants. Castiel eventually became the Captain of his Garrison. It is likely Anna Milton held that rank, before she fell. The highest ranking officer of the garrison, usually the captain, reports to their superior, higher, more powerful angelic beings known as seraphs, who rank as Colonels. They in turn report to the archangels; the generals. Raphael would probably rank as a Major General, or possibly a Lieutenant General, while Michael, the most powerful celestial would rank as a full, four-star General.

A secretarial division was described by Metatron, who was originally a part of the said group. Angels with higher organizational power belonged to other groups, such as the intelligence division of Naomi.

There is also a special class of angel called the Rit Zien, which, as Castiel described, function like medics, and when ever on battlefields, the tend to the wounded and heal those that can be healed.

There are angels, like Thaddeus, who are in charge of Heaven's dungeons, guarding angels and torturing them as a punishment for their crimes and disobedience, just like Gadreel and Abner.



Heaven's hierarchy is extremely strict. All the angels are expected to obey orders from their superiors and the Archangels without question. Emotions are highly discouraged amongst angels, as many of the higher ranking angels see them as doorways to doubt. Disobedience or lack of faith is punishable by demotion, banishment, torture, and even death.

It should be noted that not all angels are warriors. Some have other tasks, such as being scribes (Metatron) and gardeners (Joshua).

Heaven's hierarchy as of the current moment is unknown, as all angels but one have been cast down to earth.

Trivia

 * Ash tells the brothers that Heaven is comprised of many places, like 100 billion individual Heavens. Dean then states that everyone gets a piece of paradise, thus hinting to that Heaven is infinite. This also means that religion is not an important deciding factor for who gets in to Heaven when they die.
 * Heaven's whereabouts and state of existence in Supernatural is unclear. It is indirectly implied to be part of the same universe as Earth, and characters frequently refer to it as being above Earth and/or in the sky; and it has also been shown that when angels travel from Heaven to Earth through means other than teleportation (i.e., when they fall from Heaven) that they seem to fall to Earth from out of the sky. However, a few fans have argued that the implications at times in the show that the Supernatural universe's cosmology is like the real world's (such as Crowley's reference to the first moon landing in What's Up, Tiger Mommy?) would indicate that the sky itself isn't really Heaven itself. Some fans believe and/or have theorised that Heaven is located in a pocket reality or a plane of the universe above the earthly plane.
 * How heaven appears the individuals how they imagine maybe hell is the same how individuals imagine hell appears them like that.
