"You'd think the Angel would have been foresighted enough to give us a birth-control rune, but no dice."----City Of Fallen Angels.

For a long time since their creation, the existence of angels were mythical. It remains a widely accepted belief among Shadowhunters that they possess the blood of the Angel Raziel. Nephilim regard them as their spiritual parents, and they recognize them with their invocations, in the names of their most holy weapons, and some in their prayers.

The general consensus is that the physical forms of angels are shaped like humans, but are much larger, winged, and glow with heavenly fire. Many have suggested that when angels do manifest on Earth, they take whatever shape witnesses will recognize as angelic.

They possess superhuman strength beyond that of any Downworlder, Nephilim, or lesser demon. Angels of high rank,like Raziel, are supposedly strong enough to defeat the higher Greater Demons. Angels possess the abilities of Marked Shadowhunters, though at a much greater degree. Also, much like with faeries and some old warlocks, time flows or is perceived differently by angels compared to humans.

Fallen angels are angels who have been cast out of Heaven for their rebellion. It is often believed that most fallen angels are those who sided with Lucifer when he made his war against God. After they were cast into Hell and the Void, they took on monstrous corporeal forms and later became known to fall under the categorization of Greater Demons . Some of the more powerful fallen angels became Princes of Hell. These now demonic fallen angels created lesser, common demons as well as the chaotic ethereal force that animates them and gives them their powers.

Angels do not respond to summons in the same way that demons do. They cannot maintain their corporeal form on Earth for long, any more than other non-demon creatures can in a dimension not their own. The summoning rituals that claim to bring angels are obscure, difficult, and unreliable. They have been accomplished so rarely that there is not much evidence for what does and does not work.

Along with these factors, the danger and risk of disaster, injury, or death from a misunderstood or misapplied summoning ritual is very high. It is even forbidden for some angels to be summoned unless through the proper methods and in the proper time, like Raziel, who could be summoned, though infrequently, with the Mortal Instruments. When summoned without the typically-necessary tools.

Even if the summoning was successful, there is currently no known way to oblige an angel to cooperate with the desires or needs of the summoner. An angel cannot be bound in the way that a demon is bound, except by the application of forbidden and blasphemous rituals, such as the circle of Marks that Valentine used to bind Ithuriel and with which he attempted to use to compel Raziel, the performance of which are among the worst violations of the Law that a Shadowhunter could commit.

If a summoning is successful, the summoner and any of his/her assistants risk quick death at the hands of the summoned angel. They do not like manifesting into a corporeal form, nor do they like helping humans, and they are not known for their mercy. They are deeply indifferent to the travails of the mortal realm. They are not merely messengers or guardians, they are the soldiers of God's army and emissaries of his wrath and vengeance. They are not patient or tolerant of human vicissitudes.

Despite their intimidating appearance, some angels are not all-powerful and can be defeated. John Shade and Valentine Morgenstern were both able to summon Ithuriel. Seraph blades are somehow deadly to an angel's corporeal form. When angels make promises, they are tied to it and its conditions, meaning they will not be allowed to break it.

Shadowhunters are required to know the names of the angels. One reason is they learn their names out of respect. It is believed that the seraph blades are infused not just with the generic heavenly fire of adamas, but with some of the spirit of the angel named. Nephilim rarely name their seraph blades after the most famous and powerful of angels due to fear.
